Ken--I'm convinced that any planning Hussein did for a post-invasion insurgency was limited and ineffective. He was much more concerned that U.S. action would provoke another Shiite uprising. That was what he was configured to deal with.

I've never seen anything that indicates that there was a plan to invade six months earlier. But even if there had been, it wouldn't have mattered. The primary causes of the insurgency was Sunni Arab resistance to their loss of domination, and the desire of the transnational jihadist community to strike at the United States. Six months or six years in either direction would not have altered these conditions.
