Kristof has a rather naive view of things:
Instead of protecting its borders, Iraq will hide its army within its cities, where air strikes are effective only at an unacceptable (for America) cost in civilian deaths. Saddam has a hiding place for himself that is better than Osama bin Laden's caves at Tora Bora: the teeming city of Baghdad, with five million inhabitants, where he already never spends two consecutive nights in the same place.

I appreciate that our military makes an effort to avoid civilian casualties, but he makes it sound as if we never bomb cities.
