They can prosecute all they want but nothing will happen
Of course you are right, but why do you find it acceptable that the US is not accountable for its perversion of internationally accepted behavior?
It is not acceptable, but it is reality.
So I will ask again. You are okay with Americans being put on trial for war crimes?
That was not your question, but I am happy to answer.
I think it very appropriate for Americans to be put on trial for war crimes. The problem would be the power elite would see to that only low level Americans be prosecuted. The real culprits like FDR, Truman, LBJ, W, BO, Hillary, etc....would be protected. Imagine the limiting affect on future pols, if leading American politicians were languishing in prison. It just might put an end to war altogether.
