EDITORIAL: France Seizes Its Fifth Phantom Tanker — Macron Declares War on Putin's Money

Introduction: The Ship That Shouldn't Have Been There

A boarding in Sicilian waters

On June 24, 2026, the French navy stopped a ship called the Deliver. It was flying a Cameroonian flag. It had departed from Primorsk, a Russian oil terminal on the Gulf of Finland. It was carrying crude oil. And it had absolutely no legitimate reason to be in those waters if not for the elaborate sanctions-evasion machinery that Russia calls its shadow fleet — a sprawling network of aging tankers, obscure flag registries, shell companies, and complicit intermediaries designed to keep Russian oil moving to world markets despite the price cap and sanctions regime imposed by Western allies after the full-scale invasion of Ukraine.

The French navy's boarding of the Deliver was not a surprise interception. It was the fifth such seizure by French naval forces in nine months — a systematic campaign that President Macron has explicitly framed as a declaration of intent. "We will not allow the shadow fleet to circumvent sanctions," he said. Those are not the words of a government performing compliance theater. They are a statement of operational policy with real ships at the end of them.

The fifth seizure in nine months

France began this maritime enforcement campaign in September 2025. Each seizure has added to a documentary record: the names of the ships, their routes, their cargoes, their flag registries, their beneficial ownership structures. By the fifth boarding, the French navy has accumulated operational experience, legal precedent, and intelligence about the shadow fleet's operating methods that is already influencing how other European maritime nations approach the same problem.

The pattern of five seizures in nine months is also a political signal: this is not a one-time demonstration of resolve that fades after the press conference. It is a sustained enforcement posture. France has decided — and has now demonstrated four times before this fifth instance — that it will board, detain, and prosecute vessels moving sanctioned Russian oil. That consistency matters more than any individual seizure.

What the Shadow Fleet Actually Is

The anatomy of a sanctions-evasion network

The shadow fleet is not a monolith with a central command structure. It is an ecosystem — an informal network of convenience that serves Russia's oil export needs by assembling, from existing components, a system that is technically outside any single jurisdiction's control. The ships are typically old, often beyond standard insurance coverage, registered under flags of convenience in countries with minimal maritime oversight. The beneficial owners are buried in corporate structures that span multiple jurisdictions, often with nominee directors and opaque shareholding. The insurance is provided — if at all — by non-Western underwriters operating outside the International Group of P&I Clubs.

Before the full-scale invasion, Russia exported approximately 5 million barrels per day of oil and refined products. The G7 price cap, imposed in December 2022, was designed to allow Russian oil to continue flowing to prevent global price shocks while capping the revenue Russia received per barrel. The shadow fleet emerged as Russia's mechanism for escaping the cap: by using ships and financial intermediaries outside Western jurisdiction, Russia could sell its oil above the cap price to buyers in India, China, Turkey, and elsewhere without relying on the Western shipping insurance and financing that the cap was designed to leverage as enforcement tools.

The Deliver's specific profile

The Deliver fits the shadow fleet profile precisely. Cameroonian flag — a registry with minimal oversight capacity and no ability to effectively monitor a global tanker fleet. Departure from Primorsk — a major Russian oil loading terminal. Cargo of crude oil — subject to the G7 price cap if using Western services. Presence near Sicily — suggesting a destination in the Mediterranean or beyond, possibly for ship-to-ship transfer to obscure the origin before final delivery.

Ship-to-ship transfers — conducted at sea, away from port monitoring — are one of the shadow fleet's most common techniques for obscuring the origin of Russian crude. A cargo loaded at Primorsk can be transferred to a second vessel in Greek or Turkish waters, with the second vessel presenting paperwork showing a different origin port. By the time the cargo reaches its final buyer, the Russian origin has been effectively laundered from the documentation. France boarding the Deliver before that transfer could occur preserved the evidentiary chain.

The UK's Smyrtos Seizure: A Parallel Enforcement Track

Forty-six million pounds of Russian crude

France was not alone in the mid-June 2026 maritime enforcement surge. On June 14 — ten days before the Deliver boarding — the UK Royal Navy detained the tanker Smyrtos, carrying 98,000 tonnes of Urals crude oil with an estimated market value of approximately 46 million pounds (or roughly 58 million dollars at prevailing rates). The ship's captain, an Indian national named Ajay Pant, was detained by British authorities.

The Smyrtos seizure is significant for reasons beyond the cargo value. The detention of a ship's captain — a named individual, in a named jurisdiction, facing named charges — converts the shadow fleet enforcement operation from a property seizure into a personal accountability exercise. Shipping captains talk to other shipping captains. Word moves through the maritime industry's informal networks that sailing a shadow fleet tanker can now result in personal detention in a Western jurisdiction. That human deterrent dimension of the UK operation may prove more effective than the seizure itself in changing behavior.

The intelligence value of seized ships

Every seized shadow fleet vessel is also an intelligence asset. Its navigation systems, communications records, cargo documentation, and crew statements provide information about the broader network: which intermediaries arranged the cargo, which insurers covered the vessel, which port agents facilitated the loading, which buyers were the intended recipients. This intelligence, properly exploited, can map the shadow fleet's operating structure in ways that strengthen future enforcement operations and provide the evidentiary basis for additional sanctions designations.

The UK government's decision to publish details of the Smyrtos seizure — including the captain's name, the cargo volume, and the estimated value — reflects an understanding that the deterrent effect of enforcement depends on visibility. Quiet seizures that disappear into administrative proceedings do not send signals to shadow fleet operators. Public seizures with named individuals and documented cargoes do.

Macron's Strategic Calculation

Why France is leading the maritime enforcement effort

France's emergence as the most active European naval enforcer of oil sanctions against Russia reflects several converging considerations. President Macron has spent three years managing a complicated public posture on Ukraine — initially seeking to maintain dialogue with Putin, then hardening his position following the failure of those efforts and the evidence of Russian atrocities in Bucha and Mariupol, and now positioning France as an active military and financial partner for Ukrainian defense. The maritime enforcement campaign is consistent with this trajectory: it is visible, it is costly to Russia, and it requires naval capacity that France has and many European partners do not.

France doubled the financial penalties for shadow fleet violations in April 2026 — a legislative signal that preceded the fifth boarding and that reflects a domestic political consensus around tighter enforcement. The French parliament and public have, in ways that were not predictable in 2022, consolidated around a harder line on Russian sanctions evasion. Macron is executing policy that has real domestic support rather than leading an isolated executive initiative.

The limits of unilateral naval enforcement

France cannot fix the shadow fleet problem alone. The network involves ships registered in Cameroon, Gabon, Palau, Belize, and a dozen other flag states. It uses financial intermediaries in Turkey, India, the UAE, and Hong Kong. It sells to buyers in China, India, and Southeast Asia. The enforcement jurisdiction that France, the UK, and other European navies can exercise covers a fraction of the routes these vessels use and a fraction of the transactions that sustain them.

Effective shadow fleet disruption requires coordination: with Turkey, which controls the Straits and through which much shadow fleet traffic must pass; with India, which has become Russia's largest oil customer; with China, which has absorbed the surplus that European buyers relinquished; and with the flag states whose registries provide the legal cover that makes the whole system work. None of those conversations are moving at the pace that France's boarding tempo implies would be necessary for systemic change.

Washington's Contradictory Move: Removing Entities from Sanctions Lists

The June 25 removals and what they signal

On June 25, 2026 — one day after France boarded the Deliver — the US Treasury Department removed seven Russian individuals, two ships, and two Turkish firms from its sanctions list. The timing is, to put it gently, unfortunate. Whether the removals reflect a deliberate policy signal, a routine administrative process, or a diplomatic accommodation of Turkish interests in the context of broader negotiations is not entirely clear from the public record. What is clear is that the juxtaposition — Europe enforcing, America relaxing — plays directly into Russia's preferred narrative about Western incoherence.

The two Turkish firms removed from the sanctions list are particularly significant given Turkey's role in the shadow fleet ecosystem. Turkey has been a major facilitator of shadow fleet operations: its ports have served as transfer points, its shipping companies have provided logistical services, and its financial system has processed transactions that European banks would have declined. Removing Turkish entities from the US sanctions list, at a moment when France and the UK are boarding ships, is the kind of policy dissonance that sanctions practitioners describe as "one hand undoing what the other hand does."

The political economy of US sanctions policy

US sanctions policy on Russia has been under sustained pressure from multiple directions since early 2025. The Trump administration has shown a consistent interest in reducing the economic isolation of Russia as part of broader diplomatic engagement. Agricultural interests, energy sector lobbying, and geopolitical considerations involving Turkey's NATO membership have all created constituencies within the US government for sanctions relaxation. The June 25 removals are not an isolated event. They are a data point in a trend.

For Ukraine's allies in Europe, this trend is a source of genuine strategic anxiety. The sanctions regime's effectiveness depends on its comprehensiveness: partial enforcement creates arbitrage opportunities that Russia exploits. When the US removes entities that European partners are actively enforcing against, it creates legal and diplomatic complications that undermine the coalition's collective position. The consequences of that incoherence are paid, ultimately, by Ukraine.

Russia's Response: Calling It Piracy

Moscow's legal framing of the boardings

Russia has characterized France's maritime enforcement operations as piracy — an accusation that is legally unsupportable but rhetorically useful. Under international maritime law, states have the right to board and inspect vessels suspected of sanctions violations in their territorial waters or in international waters where there is a valid legal basis for the exercise of jurisdiction. The legal frameworks underpinning the French boardings — EU sanctions regulations, UN Security Council resolutions, and bilateral enforcement agreements — are extensive and well-documented.

Russia's piracy characterization serves a specific purpose: it frames Western sanctions enforcement as an act of lawlessness by states that have abandoned the rule of law in favor of political hostility. This framing is consumed primarily by audiences in the Global South, where historical grievances about Western economic coercion make it more resonant than it would be in a European context. Russia's information strategy around sanctions enforcement is not aimed at convincing Western publics. It is aimed at the countries in Africa, Asia, and Latin America that Russia needs as alternative markets and diplomatic partners.

The effectiveness of the piracy narrative

Whether the piracy narrative is working is genuinely uncertain. Some Global South governments have been receptive to Russian framing of Western sanctions as economic aggression. Others have been less so — particularly those that have experienced Russian aggression directly or that have strong commercial relationships with the West that they are unwilling to jeopardize. The UN General Assembly votes on Ukraine-related resolutions have consistently shown a majority that supports Ukrainian territorial integrity, even if that majority does not translate into active sanctions enforcement cooperation.

The more immediate effect of the piracy narrative is domestic: it gives Russian state media a frame for presenting the maritime seizures to Russian audiences as external aggression rather than consequences of Russia's own illegal war. Whether those audiences believe it is a separate question from whether the frame serves its intended function in sustaining domestic support for the conflict.

The Shadow Fleet's Economic Impact: What Russia Loses

Oil revenue and the war economy

Russia's federal budget depends heavily on oil and gas revenues — estimates from the IMF and the Kyiv School of Economics have consistently placed hydrocarbon receipts at 30 to 40 percent of total federal budget revenues during the war years. The price cap, when enforced effectively, was designed to allow Russia to continue exporting oil while capping the per-barrel revenue, thereby reducing the funds available for military spending. Shadow fleet enforcement that disrupts this evasion mechanism — even partially — has direct implications for Russia's ability to finance the war.

Each seized tanker represents not only a lost cargo but also a lost ship, a lost captain, and a reputational event that raises the risk premium for every shadow fleet operator. Insurance costs increase. Charter rates increase. Flag registries face political pressure to tighten oversight or risk losing access to Western ports. The cumulative friction imposed on the shadow fleet by five French seizures and one UK seizure does not shut the network down. But it raises costs, which reduces margins, which reduces the attractiveness of the business to the marginal operators who keep the network running.

The Urals discount and its limits

Russia has responded to the price cap and shadow fleet pressure by accepting a wider discount on Urals crude relative to Brent benchmark pricing — essentially selling oil more cheaply to buyers who accept the political and reputational risk of purchasing sanctioned Russian energy. This discount has been significant at various points in the war, representing an implicit tax on Russia's oil export revenue that accumulates over time.

The discount is not infinite. As Western enforcement intensifies and as more flag states and insurance providers distance themselves from shadow fleet operations, the pool of buyers willing to absorb both the discount and the reputational risk narrows. The long-term trajectory of the shadow fleet — absent a ceasefire that removes the political rationale for sanctions — is toward progressive constriction. France's boarding tempo is a factor in that trajectory, even if it does not determine the outcome alone.

European Maritime Solidarity: Who Else Is Acting

The coalition of enforcers

France and the UK are not the only European states moving on shadow fleet enforcement, but they are the most active. Germany has tightened its port inspection regime for vessels suspected of shadow fleet involvement. The Netherlands, which hosts the port of Rotterdam — Europe's largest — has implemented enhanced due diligence requirements for tanker traffic with Russian origin indicators. The Baltic states, led by Estonia, have been among the most vocal advocates for aggressive enforcement and have conducted their own maritime interdiction operations in Baltic waters where Russian shadow fleet transit is most visible.

The European Maritime Safety Agency (EMSA) has expanded its monitoring of vessel tracking data — specifically, the AIS spoofing and dark ship practices used by shadow fleet vessels to hide their movements. Several dozen vessels have been flagged for investigation based on anomalous tracking behavior in European waters. The data infrastructure for enforcement has improved significantly since 2023. The political will to act on it has lagged behind the technical capacity, but the France-UK enforcement tempo is beginning to pull other partners in the same direction.

The insurance market as an enforcement lever

Beyond direct naval enforcement, the maritime insurance market represents perhaps the most powerful civilian lever for shadow fleet disruption. The International Group of P&I Clubs — the consortium of mutual insurers that covers roughly 90 percent of the world's ocean-going cargo — has collectively refused to insure vessels engaged in sanctions-violating Russian oil transport. This creates a genuine financial constraint: shadow fleet operators must either operate without adequate insurance (which many ports of call require as a condition of entry) or rely on inferior alternative coverage that commands higher premiums and provides weaker protection.

The Lloyd's of London market has also tightened underwriting standards for vessels with Russian origin exposure. These market-driven constraints, operating alongside state enforcement, compound the cost of shadow fleet operation in ways that no single government action achieves alone. The combination of French naval boardings and British insurance market pressure is more effective than either would be in isolation.

The Flag State Problem: Cameroon, Belize, and the Registry Business

Who provides the legal cover

The Deliver's Cameroonian flag registration is not an accident. It is a commercial transaction. Cameroon, like Belize, Palau, the Marshall Islands, and a dozen other states, operates an open ship registry as a revenue source — a service business that provides flag-of-convenience registration to vessel owners worldwide in exchange for fees. The regulatory capacity and political will to actually monitor and sanction vessels registered under these flags varies enormously, but in many cases the oversight is minimal and the registry operates primarily as a revenue stream disconnected from any genuine maritime governance function.

Shadow fleet operators select these registries precisely because they offer registration without scrutiny. A tanker registered in Cameroon faces no realistic prospect of Cameroonian maritime inspectors boarding it in the Black Sea to verify its cargo. The Cameroonian government has no navy, no maritime patrol capacity, and — until recently — no political incentive to refuse registration to vessels whose operators are paying the fees.

The pressure campaign on flag states

Western governments have begun applying pressure to the most commonly used shadow fleet flag states, with mixed results. Palau, under significant US diplomatic pressure, announced in early 2026 that it would de-register vessels found to be engaged in sanctioned Russian oil transport. Several other small registry states have made similar announcements. Whether these announcements translate into actual de-registrations, and whether shadow fleet operators simply migrate to alternative registries, is an ongoing empirical question.

The EU has proposed a regime of secondary sanctions that would penalize companies and individuals in third countries that facilitate shadow fleet operations — an extension of enforcement jurisdiction beyond EU territory that has been contested both legally and diplomatically. If implemented, secondary sanctions would change the calculation for flag states significantly: the cost of hosting shadow fleet vessels would include not just reputational risk but concrete financial penalties. That change in the cost structure, more than any individual boarding, would be the inflection point for shadow fleet disruption.

The Legal Architecture: Sanctions, International Law, and the Gaps

The legal basis for French enforcement

French naval enforcement of EU oil sanctions rests on a combination of legal instruments: EU Council regulations imposing the price cap and prohibiting transport services for Russian oil above the cap; French national legislation implementing those regulations with criminal penalties; and the general provisions of international maritime law governing the right of states to exercise enforcement jurisdiction over foreign vessels in certain circumstances. The legal framework is genuine and defensible, even if Russia frames it as piracy.

The most legally complex dimension of the French operations involves jurisdiction over vessels in international waters flying the flag of a third state — in the Deliver's case, Cameroon. The boarding of a foreign-flagged vessel on the high seas generally requires either the flag state's consent, a UN Security Council authorization, or a specific treaty basis. France has navigated these requirements in each of its five seizures, but the specific legal basis for each boarding is not always fully disclosed in public statements. The legal architecture is real; it is also not unlimited.

The precedent being established

Five French boardings and one UK seizure in the space of nine months are establishing a precedent: that European states will use naval force to enforce sanctions against shadow fleet vessels operating in European waters. This precedent has implications beyond the individual seizures. It signals to flag states, ship operators, and financial intermediaries that the enforcement regime is real. It creates judicial precedents as individual cases work through the French and UK legal systems. And it demonstrates to other European naval powers what effective enforcement looks like in practice.

The precedent will also be tested. Russia, Cameroon, and individual shipping companies may challenge the legal basis of specific seizures in international fora. Those challenges will generate legal arguments that clarify and potentially constrain future enforcement actions. The legal architecture of shadow fleet enforcement is being built in real time, through the accumulation of cases, and France is currently writing more of it than anyone else.

The Broader Sanctions Regime: What Is Working and What Isn't

The price cap's mixed record

The G7 price cap on Russian oil, set at 60 dollars per barrel for crude, was designed to reduce Russian revenue while avoiding the global price shock that a complete embargo would have caused. Its effectiveness has been debated continuously since implementation. On the positive side: Russian oil revenues have been reduced from pre-war levels, the Urals discount relative to Brent has been significant, and the shadow fleet's costs have increased substantially compared to a world without enforcement. On the negative side: Russia has adapted, the discount has narrowed as alternative markets deepened, and the cap has been widely violated without consistent consequences.

The maritime enforcement operations by France and the UK represent the most tangible evidence that the cap can be enforced rather than merely declared. But the scale of enforcement relative to the scale of evasion is still grossly disproportionate. Five French seizures against a shadow fleet estimated at 600-plus vessels is a deterrent signal, not a system shutdown.

What would be needed for a systemic solution

Analysts at the Kyiv School of Economics, the Atlantic Council, and the CSIS have consistently identified the same set of requirements for making the oil sanctions regime genuinely effective: Indian and Chinese participation or at minimum abstention, Turkish cooperation on transit monitoring, consistent US enforcement without the kind of inconsistency demonstrated by the June 25 removals, secondary sanctions that change the calculus for third-country facilitators, and a coordinated crackdown on the insurance and financial infrastructure that sustains shadow fleet operations.

None of these conditions are currently in place simultaneously. Some may not be achievable under current geopolitical conditions. The practical implication is that the sanctions regime will continue to function as a partial constraint on Russian oil revenues — significant but not decisive. France's five boardings are real, consequential, and insufficient. That combination is the honest summary of where enforcement stands.

The Five Seizures: A Statistical Portrait

What nine months of enforcement has produced

France's five seizures between September 2025 and June 2026 represent an unprecedented tempo of European maritime enforcement against sanctions violations. The vessels detained span multiple flag registries — a pattern that reflects the shadow fleet's deliberate diversification of risk across different national legal systems. The cargoes documented range from Urals crude to refined petroleum products. The destinations, where documented, include Mediterranean transfer points, refineries in third countries, and — in at least one case — a direct delivery attempt to an EU member state port.

The financial value of the cargoes seized — while not comprehensively published — represents tens of millions of dollars in denied revenue to Russian export networks. The administrative and legal costs imposed on shadow fleet operators, insurers, and intermediaries add to that figure. The reputational cost — the designation of specific vessels and operators as actively targeted by French naval enforcement — adds a further deterrent premium to any future shadow fleet operation in European waters.

What the sixth seizure will look like

Given the pattern established over nine months, a sixth French seizure in the coming months is more likely than not. The French navy has demonstrated that it has the operational capacity, the legal framework, and the political mandate to continue. The shadow fleet has not retracted from European waters in response to the first five boardings — which means the targets remain available and the enforcement mandate remains active.

The question for the next seizure is whether it will produce anything new: a higher-profile vessel, a more significant cargo, a flag state whose involvement creates additional diplomatic leverage, or a beneficial ownership disclosure that reaches further into the Russian financial system. Each seizure produces intelligence. That intelligence is being used. The trajectory is toward more specific targeting rather than more volume — quality of enforcement replacing pure quantity as the primary variable.

France's Political Calculus: Macron Consolidates His Atlanticist Stance

The shadow fleet as a domestic policy asset

It would be naive not to note the domestic political dimension in Macron's communication on these seizures. In France, support for Ukraine is broadly shared in public opinion, even if certain political formations — on the far left and far right — maintain more ambiguous positions on relations with Russia. The naval interventions against the shadow fleet allow Macron to embody an active, visible, and morally unambiguous European leadership.

Announcing these seizures personally — and announcing them with forceful formulations ("we will not allow this") — allows the Élysée to build a narrative of strength and coherence in French foreign policy. This is not pure communication: the actions are real. But the communication is chosen, calibrated, and it also serves a domestic political agenda.

France as Europe's leading military power

These operations also consolidate France's position as the principal military power of the European Union — especially since Britain's departure. France is the only EU member with a genuine naval power-projection force capable of operating in the Mediterranean and the Atlantic. These seizures demonstrate that this capability is being deployed for strategic purposes, not merely for exercises or colonial-era order-keeping in overseas territories.

In the context of the accelerated European rearmament since 2022, a France that seizes Russian oil tankers sends a message to Berlin, Rome, and Warsaw: French military power is in service of the collective defense of European values and interests. It is a gunboat diplomacy modernized for the twenty-first century.

Toward Total Maritime Economic Warfare

The cascading escalation

The current dynamic tends toward progressive escalation. France seizes five vessels; Russia calls it piracy; the West prepares the legal framework to go further. The United Kingdom is considering selling the Russian cargo to fund Ukraine; Moscow threatens legal action; Western allies debate extending the precedent. Each action calls for a reaction that justifies the next action. This is the escalation logic of economic warfare.

We must be clear-eyed: Moscow can also adapt. The shadow fleet can change its routes, avoid waters under French or British surveillance, transit through straits beyond the reach of Western navies. The Arctic, the Strait of Hormuz, Indonesian waters — there are corridors the West does not control. Economic warfare will never be won by a single blow, however decisive.

Victory is measured over the long term

What matters, ultimately, is the long-term trend. Can Russia continue to finance its war indefinitely with a degraded oil apparatus, struck refineries, a hunted shadow fleet, frozen monetary reserves, and a sanctioned economy? The answer, according to every available indicator, is no — but not yet.

Ukraine needs time. The West needs courage and consistency. The French navy seizing the Deliver off Sicily is a small victory in a very long war. But it is part of an accumulation of pressures that, together, are drawing the future of this conflict. Every seized tanker, every prosecuted captain, every blocked dollar of oil revenue is one more brick in the economic wall that, slowly and inexorably, will change Moscow's calculus.

Conclusion: Accountability Has a Name, a Flag, and a Cargo Manifest

The value of making the abstract concrete

Sanctions debates are often conducted in the language of policy mechanisms — price caps, secondary sanctions, designation criteria, enforcement jurisdictions. That language is necessary and important. It is also capable of obscuring the fundamental moral question that France's maritime enforcement campaign makes concrete: are there consequences for helping Russia fund its war against Ukraine, or are there not?

Five French boardings and one UK seizure say: yes, there are consequences. They are physical consequences — a ship detained, a cargo seized, a captain held for questioning, a voyage terminated. They are financial consequences — a lost cargo, an increased insurance premium, a reputational cost that raises the price of the next evasion attempt. They are legal consequences — a proceeding in a French or UK court, a precedent established, a judgment recorded.

What accountability requires to succeed

Accountability at this scale — a six-hundred-ship shadow fleet sustained by global financial networks — requires more than France can provide alone. It requires the kind of coalition enforcement that the sanctions regime was designed to produce and has only partially delivered. It requires consistency from Washington at the same moment that Paris is boarding ships in the Strait of Sicily. It requires India and China to accept that buying sanctioned Russian oil has costs that their own interests eventually cannot absorb. It requires Turkey to choose between its NATO membership obligations and its commercial convenience as a shadow fleet transit hub.

None of those requirements are fully met today. What France has done is demonstrate that meeting them is possible — that a Western government can make a political decision to enforce its own rules at sea, can develop the operational capacity to do it consistently, and can survive the Russian accusation of piracy with its legal and diplomatic standing intact. That demonstration is not the solution to the shadow fleet. It is the proof of concept. The question is whether enough other actors will follow the example before the war's outcome is decided.
