I had the same thoughts watching this unfold. In this specific instance, perhaps a little celebrating is appropriate.
When other countries celebrated the attacks on the US, it involved, essentially, innocent people being killed. never once has anyone in the US celebrated civilian deaths during our wars or conflicts or whatever we call them. Almost the opposite of other countries, we lash out at our own troops and govt when civilians are involved.
Osama is different. He fully admits and takes credit and even relishes in the murders and atrocities his organization has carried out throughout the entire world. I don't think anyone doubts that he would have struck again if he could have and was actively planning to try and do so. Surprising to many here, I am not an advocate of the death penalty, however, Osama is a different case. I sure would not have wanted any Americans dieing trying to arrest him if killing him saved lives.
Our celebrating is not, or at least should not be, directed at anything Arab or Muslim, but rather directed at just the man, Osama. Other countries people seem to celebrtae anything bad happening to our country. A big difference in my mind.
