"President Putin's war of aggression against Ukraine is the biggest security crisis in Europe since the Second World War. It is not only a direct threat to the existence of Ukraine as a free and independent country, but to the entire rules-based international order. Putin must not win. If he does, it will show that aggression works and that force is rewarded. This would be dangerous for our own security, and for the whole world. This war did not start in 2022, it started in 2014, when Russia illegally annexed Crimea and entered eastern Ukraine. Since then, NATO Allies have trained tens of thousands of Ukrainian soldiers and supported its defence and security sector. NATO will continue to stand by Ukraine for as long as it takes."
