I am no more celebrating the death of Osama bin Laden than I celebrated the death of Idi Amin or Saddam Hussein. Saddam had a trial, in his own country, and he was punished under his country's laws. Amin died a "natural death," as I remember. bin Laden had declared "a Holy War" against the US:

"We declared jihad against the US government, because the US government is unjust, criminal and tyrannical. It has committed acts that are extremely unjust, hideous and criminal whether directly or through its support of the Israeli occupation."
                      - Osama bin Laden - to CNN in March 1997

If someone declares war on me and takes violent actions against me I will defend myself as I find appropriate to the situation. Whether or not this applies to nations I don't know.

I do know that a human being (three or four, actually -- I've read different accounts) was killed in a firefight. I can wish that that person had been taken alive, but he himself said

We love death. The U.S. loves life. That is the difference between us two.

Some do not believe he is dead: he is. This is the man who said

I'm fighting so I can die a martyr and go to heaven to meet God. Our fight now is against the Americans.

All I can say is that he got his wish. I neither lament nor rejoice; I only hope that his death helps lower the level of terrorism in the world. It will never go away -- there is no guarantee of safety and security and there never was.

What I do hope is that the combat in Afghanistan and elsewhere ends soon.
