Basically, they are saying Russia can invade any country because it has nuclear power. The fact is the Russian won't listern to anything unless you use '最后通牒口吻'. Kenndy used it and he won, Reagan used it and won again. Obama is too timid to use it, so he will lose.
We are entering a world without police, law and order. Any stronger countries can occupy weaker countries any time with no consequence. Very soon, the world will become a total chaos, and then ends.
