we invaded iraq years ago, and have pretty much caused the upheavals in that entire region, destabilizing much of the area.
now what?
after ww1, we didn't get involved in another conflict til ww2. we've pretty much been in one conflict after another since then. why? why did our foreign policy change after ww2, and become the huge mess it's been ever since?
