"WE" are most certainly better than "they" are, but the motto of the jungle (I dare say the battle of Fallujah resembled a sandy jungle) is SURVIVAL OF THE FITTEST.
Therefore, the fact that the Marine DIDN'T wait to see if this guy was going to blow himself, the reporter, and the rest of he buddies, to smithereens, mean they SURVIVED to live and fight another day.
Case Closed.
P. S. I bet if you asked the friendly Iraqis, they would not complain that our guys were overly aggresive.

Might makes right, huh?
Sorry, but I also believe that "civilized" is a good trait, too.
