Jeffrey Sachs's October 2026 proposal, *A Framework for Peace in Ukraine*, deserves serious consideration. Ending a devastating war, preventing further loss of life and reducing the risk of escalation are worthwhile objectives. Sachs deserves credit for putting forward a detailed proposal rather than simply calling for peace without explaining how it might be achieved.

But a fundamental question remains: Does his plan deliver a sustainable peace, or does it effectively reward Russia for invading its neighbour?

Consider the concessions involved.

Under Sachs's proposal, Ukraine would adopt permanent military neutrality, abandon its ambitions to join NATO, prohibit foreign military forces on its territory and accept negotiated restrictions on its armed forces. NATO would also formally renounce further eastward enlargement.

Meanwhile, Russia would retain effective control of substantial occupied Ukrainian territory, including Crimea, although Ukraine would not be required to recognise Russian sovereignty over it. Russia would also regain its frozen sovereign assets, with sanctions lifted in stages by the end of 2027.

To be fair, Sachs does require concessions from Moscow. Russia would withdraw from certain occupied areas, accept Ukraine's prospective EU membership, agree to reciprocal military restrictions and participate in reconstruction and humanitarian arrangements.

But are these concessions genuinely comparable?

Russia would relinquish some of the territory it has seized and accept restrictions on future military activity. Ukraine, meanwhile, would accept permanent limitations on its sovereign security choices, while Russia continued to occupy significant parts of its internationally recognised territory.

This raises a troubling question about the precedent being established. If a country can invade its neighbour, seize territory and subsequently negotiate favourable restrictions on that neighbour's security arrangements, what incentive does that create for future aggression?

There is also the crucial issue of enforcement.

Sachs proposes international monitoring and security guarantees involving the permanent members of the UN Security Council, including Russia itself. However, his framework explicitly rejects Western military guarantees comparable to NATO's Article 5.

What happens if Russia violates the agreement and launches another invasion?

International observers might document the violation. The Security Council might discuss it. Ukraine would be permitted to defend itself and receive assistance. But what credible mechanism would actually deter Russia from attacking again?

These concerns are not merely hypothetical. Research by Mykhailo Soldatenko at the Carnegie Endowment highlights the failures of the Minsk agreements, while a 2026 Chatham House study warns that a poorly secured ceasefire could allow Russia to regroup and renew military pressure.

There is also a broader concern about Sachs's interpretation of the conflict. He repeatedly emphasises NATO expansion and Western foreign policy as central causes of the war. Those are legitimate subjects for historical examination, but such an emphasis risks diminishing Vladimir Putin's independent responsibility for choosing to invade a sovereign country.

The United Nations General Assembly condemned Russia's aggression in March 2022. Whatever criticisms one might have of Western policy, those criticisms do not remove Russia's responsibility for its actions.

None of this means that Ukraine must fight indefinitely or that negotiations should be rejected. Painful compromises may ultimately be unavoidable.

But a lasting peace must do more than stop the fighting temporarily. It must provide Ukraine with credible protection against renewed aggression.

Sachs's proposal offers a detailed route towards ending hostilities. What it has yet to demonstrate convincingly is why Ukraine should surrender significant security options in exchange for assurances from a state that has already violated its sovereignty.

Peace is a necessary objective. But peace without credible security risks becoming little more than an intermission before the next war.
