I have absolutely no problem understanding history, unlike some, I don't filter reality through biased goggles. And in the case of Iraq, I have quite a bit more knowledge about it than most Americans do. Funny though how everyone I know that was there and had been involved in it for years thinks the war was wrong, wonder why that is?
You seem to feel that "threat" means ability to cause significant damage to the physical structure of the United States. Sure glad others don't use that definition.
This inability of civilians to understand what is going on in combat and place into context is another reason why the military has it's own Justice System.
