The Iraqis who are suicide bombing are doing so under pressure from a leftist radical totalitarian regime.
That is different than fighting for "freedom". When fighting for freedom, a soldier is morally more perfect and righteous. They will not commit crimes against humanity because the soldier from the free state is the moral man.
That said, I would use every ounce of military training I received and would also use my extensive war experience to defend the United States if it were invaded. It would be the duty of all Amricans to do so because we are a free country, and to invade us means that the country invading was very evil and had to be destroyed.
There is no moral relativism between the invasion of Iraq and a hypothetical invasion of the United States. Iraq is a terror nation-state, while the US is a free state. If you can't see that, perhaps 1,000 MG of leftistcillin is what you need lol.
If the US was ever invaded I would be a General Officer in command of a covert light infantry division of some type.
