The EU has prepared a plan to deploy up to 15,000 EU and NATO troops to Ukraine as a deterrent force following a possible ceasefire, according to Die Welt citing European diplomats, as posted by @front_ukrainian on X between 6:16 PM and 7:15 PM UTC on December 31, 2025. French and British troops would be able, if necessary, to use force to support the truce even without a UN or EU mandate, with an invitation from Ukraine sufficing, the report stated. Discussions are ongoing for other European countries' participation, with multinational forces to ensure security from the sea, air, and neighboring states' territories; Turkey could play a significant role in the Black Sea.
