Oh, Mr. Bush. This is the enemy.
There can be no peace until such people either forsake violence or become victims of it. I wish some clerics would set up a MacMujihad where all entrants could be certified genuine mujahideen and given the choice of becoming isolated from civilised society with honorable imprisonment or an honorable death in the name of the cause. Then innocent people could go about their lives unendangered by the fanatics.
