...Iraq has been a resounding success. But then our goals were mostly to capture or kill Taliban and Al Qaeda - democracy is purely an after thought. Besides, these criminals are just capitalists - supplying product to meet demand.
Personally, I think we did the right thing by not using overwhelming force in Afghanistan. But I do think many of those dollars that are going to Iraq, could have been used much better for Afghanistan - but we weren't willing to shell out the dollars.
