Yes in my opinion he should apply to the International War Crimes Tribunal to overrule the US court decisions. Clearly the only thing he has done is to expose War Crimes committed by the US military. Doing so is a heroic act and is not in any way a crime. For the US to attempt to oppress and criminalise those who would expose war crimes, should itself be a crime against humanity.

These actions amount to criminalising those who have helped to bring to justice ex nazi's also guilty of war crimes. Just because a crime was committed by a Government or state, makes it no less of a crime.
