If they voiced some concerns over beheadings we might possibly listen to them.
Someone please tell these people to shut up. We blasted every church steeple in Normandy and Germany that was used for military purposes and we did it without hesitation. We carpet bombed Cologne and Dresden and we did it without hesitation. In fact, the Queen of England is going to a benefit concert in Berlin to raise money to complete the repairs of a cathedral in Cologne the British destroyed in WWII.
I say, we back the Iraqi's with massive air and ground firepower, let the Iraqis clean out the armaments and explosives hidden in mosques and clinics. If they get shot at by their own people, pull the Iraqi troops back and annihilate the entire structure. We would only have to do it a couple of times to get the point across. Then the Iraqis could do their job of making safe, the sick streets of Fallujah.
