well with something like this you should always be suspiscious, but if it's true then great. A military guy has died in a battle. won't stop the war and definitely wont stop terrorism, but at least it's a morale boost to some people and might possibly shorten the lifespan of the Al-Qaeda name until we get some other scary monster to hide under our beds.
The flag waving, fist pumping, america f yeah is probably going to last a while, but as far as I'm concerned revelling in the death of a human being (not an evil monster, since that doesn't exist,) when the victorious side has done its fair share of both civilian casualties and civil rights violations is a bit hypocritical.
Not saying his death is a bad thing, just asking people to have a little balance. It's a screwed up situation and the faster it ends, the better.
