Sometimes a war is justified, and coming to the aid of an ally getting invaded is a damn good justification.
Especially if that ally is simply asking for more hardware and not asking for feet on the ground.
Edit: Fixed the link, it was broken for some reason though it worked earlier today. IDK this mirror should work though
That’s why the udssr where allied with Hitler early in the war and signing a NAP, only stopping because Hitler betrayed them and attacked anyway?
Sorry, but this interpretation sounds a bit revisionistic. It was lot of people’s fault that Hitler could do what he did, that’s not a east vs. West thing. People should focus on the real factors and watch that something like this never happens again.
