I have witnessed Ukraine transform from a collapsing part of the Soviet Union to a liberal democracy and an open society. It has faced countless acts of Russian aggression, but has persisted. Brave Ukrainians are now on the frontline and risking their lives. The horrible images coming out of Ukraine remind me of war torn Budapest in 1944 and the siege of Sarajevo in 1993. It is important that both the transatlantic alliance (the United States, Canada, the European Union, and the United Kingdom) but also other nations do whatever is in their power to support Ukraine in its time of existential threat. Putin’s actions are a direct attack on the sovereignty of all States that were once in the Soviet Union, and beyond. Russia is in clear violation of the United Nations charter and should be held accountable. Allowing Putin to succeed on his quest will send a message across the world that nations can simply be created or dissolved by brute force. We must stand with Ukraine, as they stand for us.
