I remember hearing accounts of certain people celebrating in streets in our town after the events of September 11, 2001.
Happy to see the empire brought low. A win in the holy war against the infidels.
Not too different from today, except the celebration was on the other side of the camp.
Somehow I can't imagine Jesus jumping around in the streets waving flags and celebrating the death of any of his enemies - and he had many. Whenever I think about Him, I think about forgiveness.
There is so much more I could say, but on reflection, everyone else seems to be saying plenty. I don't feel the need to argue with conspiracy theorists or play the Pharisee. I'll just finish with something Jesus said:
"But I say, love your enemies! Pray for those who persecute you! In that way, you will be acting as true children of your Father in heaven. For He gives his sunlight to both the evil and the good, and he sends rain on the just and the unjust alike." -Matthew 5.44-45
