As a former combat soldier, and one of the few on this forum that was in combat in the region during the peak of it all, I'm happy that we're leaving. Should never have been there after intel said OBL was in Pakistan (sometime after Jan 2002), and we should never have gone into Iraq at all (what was the point again?).
It's obvious that not many people care about the region in any meaningful way. Sure, we sent contractors to sow money like seeding a field of hay; we sent relief to everyone (deserving or not) who often as not, spent it like drunken sailors. No different than any other place I suppose, but without any oversight, giving money is always a stupid idea. Leveraging money to attempt to change people only makes them dependent on the money....not any wiser, more humanitarian or generally better off.
It sure made a lot of contractors and manufacturers rich. More than a few locals skimmed their share as well. I guess they'll be forever grateful, but not so much the rest though.
Perhaps next time try invading with farmers, veterinarians, scientists, doctors, business entrepreneurs and engineers instead of money and bullets. It might work better. At least when your done they can feed themselves, and they likely won't hate you for it.
