Absolutely! Our occupying forces leave Iraq. Soon afterward, Iran takes advantage of the chaos and anarchy to ally with its neighbor, helping to rebuild Iraq right where we left off. These two powers quickly amass and send troops into Kuwait. Suddenly, Iran controls the vast majority of oil in the Middle East.

Not only would the US be hit hard as a direct result of the sanctions, but indirectly as well, since the economic turmoil in our foreign business partners would be reflected back upon us.
