no the war's over. It's the post-war that's hurting us bad and we're in middle of Civil War now. This is actually first time for us to "police" a foreign nation.
if we go all-in aka Powell Doctrine... it would take several months to deploy all manpower and equipment to do that and it would cost us billions of dollars. If I recall correctly - it took us 6-8 months just to deploy 500,000+ soldiers and heavy machines.
Rumsfeld Doctrine was lightning fast and cost-effective. I was quite impressed with the tools used in war and result it yielded. Look at the result of Rumsfeld Doctrine. The war was over in just 21 days with less than half of Powell's troop.
