He certainly was! By sympathizing and speaking out on behalf of the terrorist "insurgents" in Iraq, he was harming our military service members, as well as the peaceful citizens of Iraq who want to be free of these (mostly foreign) terrorists more than we do. How many US soldiers and innocent Iraqis have died because the terrorists are continually empowered and given moral (as well as financial) support by sympathizers like Tom Fox and his ilk?
When a "citizen" (in this case, as defined by birth, not by loyalty) travels to a foreign country, particularly one where our military is actively engaged in war, and sympathizes with our enemy, giving them aid and comfort, then that person is no longer a citizen as far as I am concerned. He is a traitor. And traitors deserve to die. I find it particularly ironic -- and just -- when they die at the hands of those with whom they are sympathizing.
My regret is not that Tom Fox was killed by his fanatical, homicidal Muslim brethren, but that others like him have not met the same fate. Jane Fonda dying at the hands of the NVA/Vietcong would have been a good start.
Tough luck if that's too politically incorrect and "insensitive" for any of you.
Well, I might not have stated it in exactly those terms, but I agree with your basic conclusions. This deluded, rootless and anti-American man sought, and got, his own death.
