The United Kingdom and France have formalized a commitment to provide military support to Ukraine as part of a future peace accord, endorsed by security assurances from the United States and other allied nations. This pledge was signed in a declaration on Tuesday.

In Paris, the Coalition of the Willing adopted this declaration, outlining a framework intended to establish enduring peace between Ukraine and Russia. This framework is anchored in international law and aligns with the principles set forth in the United Nations Charter.

Russia’s comprehensive invasion of Ukraine in 2022 marked Europe’s most significant military conflict since the Second World War.

The Coalition of the Willing, backed by the United States, has finalized a security agreement for Ukraine. This agreement includes the formation of a multinational force and mechanisms to monitor a ceasefire.

Under the new accord, Ukraine’s sovereignty and its defensive capabilities are declared to be non-negotiable aspects of any peace agreement. The document emphasizes that Ukraine’s right to self-defense is crucial not only for its own security but also for the broader stability of the Euro-Atlantic region.

Under the plan, a multinational force for Ukraine would be deployed once a ceasefire is in place, aimed at deterring any Russian aggression and supporting the rebuilding of Ukraine’s military.

The force would be European-led with proposed support from the U.S.

The declaration also commits the Coalition to security guarantees that would be activated once a ceasefire begins.

These include commitments to support Ukraine militarily, diplomatically and economically in the event of a future armed attack by Russia.

A key U.S. role is outlined in plans for a continuous, U.S.-led ceasefire monitoring and verification mechanism, with contributions from partners.

The U.S. would participate in a special commission to manage ceasefire breaches, attribute responsibility and determine solutions.

Coalition members also agreed to carry on with long-term military support for Ukraine and pledged defense cooperation, including training, defense production and intelligence sharing.

Leaders also announced the creation of a permanent U.S.-Ukraine-Coalition coordination cell based at the Coalition’s headquarters in Paris.

The declaration was unveiled at a joint news conference by French President Emmanuel Macron, Ukrainian President Volodymyr Zelenskyy and U.K. Prime Minister Keir Starmer.

This followed talks in Paris which were attended by Jared Kushner and the U.S. special envoy, Steve Witkoff.
