So the US should then take steps to deal with its own war criminals. Kissinger would be a good start. I am sure Milsovic thought his trial was politically motivated. And I am sure Sadaam Hussein did also. And I am sure to the ongoing victims of Kissinger - mines and other unexploded ordinance and chemical weopons like Agent Orange are still causing Asian deaths, in rather high numbers yearly - see his lack of being prosecuted as political.
It is amazing how the political criticism suddenly appears when the US is on the table.
