Iraq — What will history say?

After 9/11 we took our revenge on Iraq.  The leader was the bad guy we said, for what? It was not 9/11.  Nevertheless, we took our revenge. We had no reason to do what we did.  Is there something wrong with us?  I think we could use some repentance and self-limitation.  Yet, times are dangerous, dangerous for all of us, and all of us are guilty. There is no blame to place on one person or another.  Understanding what might be wrong, one cannot simply be an observer.
