The lack of immunity for U.S. forces is the reason why the U.S. is withdrawing from Iraq:
BAGHDAD (AP) — Iraq's prime minister said Saturday that U.S. troops are leaving Iraq after nearly nine years of war because Baghdad rejected American demands that any U.S. military forces to stay would have to be shielded from prosecution or lawsuits.
The comments by Nouri al-Maliki, a Shiite, made clear that it was Iraq who refused to let the U.S. military remain under the Americans' terms.
A day earlier, President Barack Obama had hailed the troops' withdrawal as the result of his commitment — promised shortly after taking office in 2009 — to end the war that he once described as "dumb."
Republicans need to shut up. Once this gets around, it's going to be a big bullet in the foot.
