European allies

As of November 23, 2025, the Ukrainian government and its international allies publicly stated they would not accept territorial concessions to Russia as part of a peace settlement.

A proposed peace-plan framework includes a security assurance modeled on NATO's Article 5 that would commit the United States and European allies to regard a significant armed attack on Ukraine as an attack threatening the peace and security of the transatlantic community and to respond accordingly, including potentially through military force.

The draft framework specifies that the proposed security guarantee would have an initial duration of 10 years and could be renewed thereafter by mutual consent.

The 28-point peace plan for Ukraine includes a U.S. and European security guarantee modeled on NATO's Article 5 that would commit the United States and European allies to treat an attack on Ukraine as an attack on the wider transatlantic community.

In the context of the 2022–2025 Ukraine conflict, NATO has coordinated regular deliveries of large weapons packages to Ukraine while European allies and Canada have procured much of that equipment from the United States.
