Dig in, hold tight, and occupy Iraq right where we stand. Keep a perimeter around Baghdad, and contain the regime until we can smoke them out by restricting supplies and precision special forces raids. Better to lose up to a few hundred by snipers and ambush then upwards of 10,000 in a full-on assault. Better for political careers and legacies too...these are our family members. We've secured the realm, if necessary let's take our time in securing the regime.
