Actually, it's sort of reassuring to see American troops used to DEFEND our country instead of invading someone else's. They are, after all, the Department of DEFENSE.
As long as they don't start using them for law enforcement. Which if I heard correctly they can now do because the Posse Comitatus Act is near null and void. Congress, yes, thanks to our Dear Leader John Warner, has given the authority to the President (sound familiar?) to decide under what situations he can declare Martial Law and take your rights away. It used to be up to Congress. Our elected officials have washed their hands of that responsibility.
I was for the war in Iraq but these idiots in Congress are just giving the President too much power. If one branch has all the power where are the checks to that power?
