Whereever there were celebrations at the World Trade Center bombings, tell the occupants: you have two hours to move.

Then bulldoze the area. Make it flatter than a pancake. Salt the earth so nothing will ever grow there again. Construct a monument (visible from orbit) to the victims of the WTC bombing.

Doesn't matter if it is Egypt, Syria, Iraq, Saudi Arabia - if we have to smash the armies of a dozen Arab countries while we do it, so be it. None of this limp-wristed coalition building. By the end of it, none of the Arab countries will be our friend, but then they never really were anyway. They will be afraid, very afraid, of us. That will suffice.
