The problem was not laid out in a hushed, mahogany-paneled G7 chamber, but on a collection of whiteboards in a brightly lit university seminar room in Brussels. The atmosphere was not one of paralyzed fear, but of focused, almost exhilarating, intellectual energy. Here, a new, younger generation of international lawyers, unburdened by the institutional dogmas of the past, was not debating if the assets could be seized, but how. They approached the challenge not as a sacrilegious shattering of norms, but as an engineering problem, a complex legal and financial puzzle that demanded a creative, robust, and law-based solution.
An older, more senior lawyer on the team, a man who had worked on the post-Cold War tribunals, began by grounding the discussion in history. He scribbled "UNSC Res. 687" on the board. "This isn't without precedent," he said, his voice a calm anchor in the sea of legal complexity. "After Iraq's invasion of Kuwait in 1990, the UN Security Council explicitly created a compensation commission funded by the seizure of Iraqi oil revenues. The principle that an aggressor must be made to pay for its damages is not radical; it's established." The obvious counter-argument hung in the air: that was then, and this time, the aggressor has a veto on the Security Council.
A younger lawyer, a specialist in financial instruments, stepped up to the second whiteboard. She began to sketch out a new, more elegant path. "We can't get a UN Security Council resolution," she conceded, "but we can build a parallel, multilateral architecture." She drew a series of interconnected boxes. "The G7 nations, where the assets are held, pass coordinated domestic legislation. This isn't a unilateral American act; it's a collective act of self-defense." She drew another box below. "This legislation empowers the transfer of the assets to a newly created legal entity—let's call it the 'International Reconstruction Trust Fund for Ukraine.'" She drew a final, crucial box below that. "And the Trust is not controlled by any one state; its trustee is an impartial, respected body, like the World Bank, which is already managing reconstruction projects on the ground." It was a blueprint for a clean, transparent, and legally defensible machine.
Then another lawyer presented the most politically savvy, and immediately actionable, proposal. He called it the "incremental route." He drew a circle on the third whiteboard, labeling it "$300bn Principal." "Let's, for the sake of argument, concede that the principal amount of the assets is protected by a strict interpretation of sovereign immunity," he said, drawing a legal shield around the circle. "But the principal is not sitting idle. Since it was frozen, it has been generating billions in unexpected, windfall profits. The interest payments, the maturing bonds—that's nearly five billion euros a year just in the assets held at Euroclear." He drew another, smaller circle next to the main one. "Our legal argument is simple and powerful. That profit is not sovereign property. It is an unexpected, un-budgeted byproduct of Russia's own illegal act of war. It does not have the same legal protection. We don't have to touch the principal yet. We start by seizing the profits."
The room buzzed with the energy of a solution found. It was an off-ramp for the paralyzingly cautious, a way to cross the Rubicon in a series of small, legally defensible steps. Start with the profits, establishing the principle. Build the international trust architecture. And then, once the machine is built and running, once the world has seen that the sky has not fallen, make the legal case for the transfer of the principal itself, not as an act of theft, but as a justified and proportional "countermeasure" under international law against Russia's ongoing, illegal war. This was not a plan to break the law; it was a plan to build the law, a creative and proactive machinery of justice to counter an act of nihilistic destruction.
The argument that seizing Russia’s sovereign assets is legally and procedurally impossible is a fiction born of political timidity, not legal reality. While the challenges are significant, a clear and robust blueprint for confiscation, operating entirely within a defensible interpretation of international and domestic law, has been developed by a formidable consensus of legal scholars and policymakers. This blueprint moves beyond the theoretical debate of if it should be done and provides a practical, step-by-step guide for how it can be done. It is a plan that offers multiple, parallel pathways, ranging from a cautious, incremental approach to a more direct and comprehensive seizure, all while grounding the action in established legal doctrines.
The most politically palatable and immediately actionable path is the incremental route, which focuses on the "windfall profits" generated by the frozen assets. The legal theory is elegant and compelling. While the principal amount of the assets—the initial $300 billion—is protected by a strict interpretation of sovereign immunity, the unexpected interest payments and dividends that these assets have generated since being immobilized are not. These profits, which amount to billions of dollars annually, are not sovereign Russian property in the same way; they are an unanticipated byproduct of the sanctions themselves, a direct consequence of Russia’s illegal war. Legal scholars in Belgium and across the EU have argued forcefully that these profits can be legally separated, taxed at 100%, and transferred to a fund for Ukraine without violating the core principle of sovereign immunity. This approach acts as a crucial first step, a way to establish the principle of "the aggressor pays" and to begin funding reconstruction without triggering the "slippery slope" fears associated with seizing the principal.
The second, more direct and comprehensive route, is based on the established legal doctrine of "countermeasures." International law is not a suicide pact. It recognizes that when one state commits a grave "internationally wrongful act" (like Russia’s war of aggression), the states that have been injured by that act are entitled to take countermeasures that would otherwise be illegal. These countermeasures must be proportional to the injury and designed to induce the wrongdoing state to cease its illegal act and make reparations. In this context, Russia's invasion is one of the most severe breaches of the UN Charter imaginable. The seizure of its sovereign assets, to be used to defend Ukraine and repair the immense damage, is a perfectly proportional and legally justified countermeasure. This is not an act of unilateral vengeance, but a collective act of self-defense on behalf of the international order and its most fundamental principles.
The execution of this seizure would be done through a transparent, multilateral architecture designed to ensure legitimacy and prevent accusations of theft. The blueprint for this machine is clear. First, the G7 nations would pass coordinated, domestic legislation giving their governments the legal authority to seize the Russian state assets held within their jurisdictions. This step provides the essential foundation in the rule of law. Second, these assets would not be transferred directly to Ukraine’s budget, but to a newly created, professionally managed, and politically impartial "International Reconstruction Trust Fund," likely with the World Bank or a similar multilateral institution acting as the trustee. This insulates the funds from potential corruption and ensures they are used for their intended purpose. Third, an international claims commission would be established to review and approve disbursements from the fund, ensuring that the money is spent on verified, specific reconstruction projects on the ground in Ukraine. This architecture transforms the seizure from a chaotic political act into an orderly, legal, and accountable process, not of expropriation, but of just compensation.
