A Mosque housing insurgents with explosives and weapons ceases to be a Holy place and becomes a fortress. The US military took great pains to avoid collateral damage, and even removed HE (high explosives) from 8 inch Howitzer shells to take out Anti-aircraft and artillery placed in sandbagged revetments next to Mosques during the war. (the empty shell hits hard) Perhaps a little more thought about enemy propaganda might be in order here. I'm sure the US troops hate to attack Mosques knowing full well the bad Karma it produces around the world; but when forced to, understand and support the actions of your troops.
