The Dead, Of Course, Have No Opinion:
Not to act like Billmon, but...

"I couldn't forget those moving scenes, blood and severed limbs, women and children sprawled everywhere. Houses destroyed along with their occupants and high rises demolished over their residents, rockets raining down on our home without mercy... And as I looked at those demolished towers...it entered my mind that we should punish the oppressor in kind." -- Osama Bin Laden, November 1, 2004.

"The enemy killed innocent men, women, and children. They filmed the atrocities, and they broadcast them for the world to see. Our enemies hope these violence images will cause us to lose our nerve and pull out before the job is done. They don't understand the United States of America. We will not run from thugs and assassins." -- George W. Bush, October 30 2006

There's a great scene in the John Woo film Face/Off where the two main characters are on opposite sides of a two-sided mirror after a massive shoot-out. The hero has had an operation where he has been given the face of the villain. In turn, the villain has taken the face of the hero. They are longtime foes, the villain having killed the son of the hero. After talking for a moment amid the broken glass and smoke, they both leap up and face the mirror. In essence, they are staring at the face of the person they hate most in the world, but, because of the operations, they are also staring at themselves. They still fire away at the mirror.
