Here, a non-american is being charged with "war crimes" not even in a properly constituted American court, but in a kangaroo court recognised by all independent legal commentators to be illegal, run by and for the forces a member of which it is alleged he killed (when fighting for a country the Americans bombed back into the stone age).
But America has refused to accept the jurisdiction of any international court (not the local courts of the victim countries, less still the properly constituted military courts of the victim countries, nor indeed any specially constituted illegal courts) over alleged war crimes by American forces.
This is not even handed. Fighting on the losing side is not a war crime.
