About as much as when Hitler marched into the Rhineland.
Of course, nobody can predict the future, and no one can say with certainty if Putin will follow the same path as Hitler.
Why is the West crying foul following the overwhelming majority of the Crimeans deciding to join their motherland Russia, when it was the USNATO that forced with bombs the cession of Kosovo from Yugoslavia.
They consider supporting Kosovo to break away from Yugoslavia, was not breaking international law, but when it comes to Crimea, then all of the sudden, international has been broken.
Freaking hypocrites.
