This piece from theWashington Post while emphasizing the difficulty and the complications of the upcoming war against Iraq, is quite good. Many things can go wrong, and some will, almost certainly. Yet it can be done. Note the last paragraph of the story:

"But perhaps the riskiest aspect of the current plan is the character and aims of the war itself, said retired Air Force Col. John Warden, an architect of the air campaign in the Gulf War.

The plan is probably one of the most risky in our history as it launches us off into terra incognita for the U.S.: our first preemptive or preventive war; our first attempt to democratize an Islamic state; and establishment of a very narrow beachhead in the midst of a billion undefeated Muslims,’ he said."
