What does my theories about International reactions on Brexit and the Irish border have to do with the legality of China using troops to forcefully break another treaty? Would China’s action become legal depending on what I answer?
I understand that, but it has nothing do with whether or not China be using force to break a legal treaty or not. Unless what you really want is to divert the discussion away from whether or not China would be breaking a treaty to cases of other nations breaking treaties.
