And how are those bridges "blown" after we are over them, pray tell?

The bridges are carefully inspected by combat engineers, and then permanently guarded.

The Iraqis have absolutely nothing capable of destroying them other than their own engineers spending hours wiring them. They're not going to get control of them again.

Nobody believes Iraq currently has nukes, and you greatly overrate the combat effectiveness of chemical weapons.

The idea of a "trap" is pure silliness.

The best "trap" is to blow the bridges before we get there and try a chem attack on the forces piled up behind them and the forces building a new bridge. Not to leave the bridge up.
