Putin didn't invade Ukraine because of NATO. He invaded because Ukrainians were proving democracy works. Historian and Pulitzer Prize winner Anne Applebaum puts it plainly: Putin looked at Ukraine's democratic movement and thought, "If they can do it in Ukraine, then people could do it in Russia. So I need to crush this." That's the real threat Ukraine posed. Not missiles. Not borders. A working democracy next door. Applebaum frames the war as a fault line between the democratic and autocratic worlds. Russia isn't just trying to take territory. It's trying to erase Ukraine as a nation, reduce it to a colony, and send a message to every country that the post-1945 rules of Europe no longer apply. Those rules were simple: no invasions, no wars, borders don't change by force. Russia understood exactly what it was breaking when it crossed into Ukraine.
