All of Europe, including the UK is ramping up their military spending, both for themselves and for Ukraine. Ukraine is the dam holding back the ruthless avariciousness and murderous intent of Putin's Russia and if that dam breaks, all of Europe is at high risk. Most especially the UK, mainly because it's an island. His avowed intent always has been to destroy the EU and western countries. He's already done that to the most powerful, ie the US. EU leaders know this is the most critical time ever.
