I’ll assume this is a real question that you actually want answered and not just a setup… 
Rumsfeld is clearly guilty of innumerable war crimes:
The Geneva Convention: Article 17, 18, 19, 20, 27, 50, 55, 56, 59, 68, 69, 147.
US Army Field Manual 27-10: US Federal law and military regulations as defined in the US Army Field Manual 27-10.
He is also guilty of breaking several international “crimes against humanity” laws that are recognized by the united states, which is far worse of an offense.
As all previous cases have ruled… “I received orders” does not absolve anyone in a command position from any of these crimes, or else every single SS officer would have been off the hook. I’m not arguing against further investigations into other involved parties, but he was the linchpin of most of this and almost all of it either originated with or went through him.
