Do you not know that the acceptability of behaviour changes with time?
You are right, Looper, but the problem is that certain countries like to tell others what the latest acceptable 'fashion' is, and they expect other countries to simply submit to their "enlightened wisdom". It's somewhat arrogant, and presumably done on purpose in order to make sure what they do is not only deemed acceptable, but also considered the morally "correct" path. They want global hegemony of what is deemed acceptable. They try to enforce their views and values on the world using any means possible.
Speaking in general you are not wrong. But let's get specific. Do you see Russia invading a neighbouring country and taking large parts of it away or destroying it as something acceptable today?
