While I agree with the sentiment here, this is pretty 1-dimensional. For one, US support of Ukraine actually has little to do with democracy and everything to do with national sovereignty. One nation with imperial ambitions invaded another nation without pretense, US provides aid to stave off that invasion.
Hypocritical given US history of imperialism? Sure. But it's NOT imperialism under the mask of democracy.
Similar arguments apply to various points on this list. Supporting NATO is about maintaining a military alliance against common enemies, not spreading democracy.
