U.K. and France Sign Paris Declaration Backing Ukraine; U.S. To Lead Ceasefire Monitoring

The United Kingdom and France on Tuesday adopted a joint declaration in Paris committing troops and concrete security guarantees to Ukraine under the terms of any future peace agreement, with key enforcement and monitoring roles to be led by the United States and allied partners.
Main Elements Of The Declaration
- Sovereignty And Self-Defense: The pact affirms that Ukraine’s sovereignty and its right to defend itself are non-negotiable, grounding the framework in international law and the U.N. Charter.
- Multinational Force: A European-led multinational force would be deployed after a ceasefire to deter renewed Russian aggression and assist in rebuilding and strengthening Ukraine’s military capabilities.
- U.S.-Led Monitoring: The United States will lead a continuous ceasefire monitoring and verification mechanism, with contributions from coalition partners and participation in a commission to investigate breaches and assign responsibility.
- Security Guarantees: Coalition members pledged predefined military, diplomatic and economic responses that would be activated if Russia renews armed attacks after a ceasefire.
- Long-Term Support: The declaration commits partners to sustained support including training, defense production, intelligence sharing and other capacity-building measures.
- Coordination Cell: Leaders announced a permanent U.S.-Ukraine-Coalition coordination cell to be based at the Coalition’s Paris headquarters to streamline planning and execution of support.
French President Emmanuel Macron, Ukrainian President Volodymyr Zelenskyy and U.K. Prime Minister Keir Starmer presented the declaration at a joint news conference. The talks in Paris were also attended by U.S. envoys, including Jared Kushner and special envoy Steve Witkoff, reflecting close transatlantic involvement in the initiative.
Context And Purpose
Officials framed the declaration against the backdrop of Russia’s full-scale invasion of Ukraine in 2022, calling it Europe’s largest conflict since World War II. The new framework is intended to provide a legally grounded, enforceable path to a durable peace while ensuring rapid, coordinated responses if hostilities resume.
What Comes Next: The pact envisions activation of the multinational force and security guarantees only after a verified ceasefire, with the U.S.-led monitoring mechanism and commission tasked with ongoing oversight and dispute resolution.
The declaration signals a deeper, institutionalized level of cooperation among Western partners to deter future aggression, bolster Ukraine’s defense over time and provide a mechanism for attribution and response to ceasefire violations.
