Ukraine's armed forces will join joint exercises with the UK-led Joint Expeditionary Force (JEF) later this year, a significant step towards deeper integration into Europe's security architecture. The move, announced during JEF leaders' meeting in Helsinki, aims to maximize operational collaboration with Kyiv. This comes as European leaders, concerned by US President Trump's lukewarm support for Ukraine and NATO, seek to ensure the country's future stability and position it as a bulwark against Russian aggression in Eastern Europe. JEF LION exercises will serve as a platform for sharing modern warfare tactics and technological innovations.

The integration effort, while symbolic, addresses a critical gap: Ukraine possesses Europe's largest army, yet US and other NATO allies have blocked its path to full alliance membership.
