So if we look the other way, we give Putin a clear signal that he can claw back the old soviet republics as he sees fit and use force with impunity. With a macho chest-beater at the helm who harks back to the old days of the soviet empire where will that end?
Alternatively the international community gets involved and we have a world war 3 kick-off scenario. This is turning ugly quickly.
