I thought he invaded because of historical and not at all unfounded fears of western encirclement. Ukraine was getting pretty close to NATO, after all. I don't doubt that there were imperialist intentions, I'm just saying there is also a certain strategy and logic to the invasion.
Hopefully this will finally teach the nations of the world they can't rely on the likes of the US for their protection. If they want to survive and keep their sovereignity, they should really start developing missile technology and stockpiling nukes. If they don't, they will simply get steamrolled by nuclear armed opponents while the US does pretty much nothing about it despite promising to because they're not actually willing to risk global thermonuclear war with Russia over some eastern european country.
