If you're not willing to untie our troops' hands you shouldn't have gone there in the first place
Exactly how have the troops hands been tied?
PC policies, the hearts & minds crap, acceding to Maliki (Sadr's proxy) "orders" by releasing a captured Mahdi army commander and taking down the US check points around Sadr City, etc.
Our troops are being murdered because they are restrained; worrying about the hearts & minds of Iraqis and the world at large.
