I hate hearing about American troop deaths.  I feel sad for the Captain and First Sergeant who died.  Those are experienced and high-ranking people.  I don't feel as sympathetic for the civilians who died.  I believe strongly that if you're going to fight a war, you fight it hard and collateral damage is expected.  We won WWII by leveling Germany and nuking Japan.  You can't try to isolate the bad guys and kill only them.  It doesn't work that way.  Killing civilians may seem harsh but it ends wars.  When you just try to fight the insurgents or guerillas, wars don't get won.  They just keep going.  And that doesn't accomplish anything but more death.
