I don't think that's quite right.

"Legitimacy" is a subjective moral argument in and of itself, and is subjective, and likely to wind up on the wrong side of history. Hiter's annexaction of sudetenland was generally discussed through the lens of legitimacy in pretty mainstream conversations. Obviously history looks at his actions through another lens.

If Russia stops at Crimea, it might be an interesting footnote or a hard pub quiz question 30 years from now. If Putin sets his sights next on Estonia, Latvia, or Lithuania, and the West lets him have it, it's going to be remembered much differently. By the way I'm not ominously promising future-Hitler. I don't think Putin wants the west, or any more than that, and I don't think any genocide is in the future.

But I do fear that he wants to rebuild as much of the former soviet block as possible, and I do think the EU won't stop him, which will itself be the final nail in the coffin of its legitimacy, and eventual dissolution.
