Keir Starmer, the UK Prime Minister, highlights Europe's unprecedented unity in response to Russia's war on Ukraine, especially after Trump's unexpected negotiations with Putin. The coalition aims to ensure Ukraine's sovereignty and prevent further Russian aggression. Key leaders, including Macron and Zelenskyy, are involved in forming a 'coalition of the willing' to support Ukraine militarily and politically. The coalition is working on three main areas: support for Ukraine's armed forces, establishing a reassurance force, and enhancing Europe's defense capabilities. The US's involvement remains uncertain, but the coalition hopes for future collaboration.
