Everybody thought that Ukraine would fall within a week but it’s been able to go toe to toe with Russia for over two years. Ukraine has every right to defend itself, destroy Russian forces invading it, and join whatever organization it wants. It’s a free sovereign nation. If spending a few billion dollars means we destroy Russia’s capacity to wage war and help Ukraine defend itself, then so be it. Russia can get fucked. They’re the aggressors and they deserve what they’re getting.
