I'm not a great signer of petitions, especially ones which say something along the lines of "this petition demands that the tide will not rise and fall tomorrow". Cnuts to that.
So, when the terrorists use innocent civilians as shields, we just turn around and walk away rather than assaulting their barricades. When the military units that actively supported the terrorists attack our forces, driving before them hundreds or thousands of innocent civilians, we either turn tail and run or just surrender gracefully, saying just before our mass executions, "We are SO sorry we bothered you. Please torture us before you hang us, and make sure our genitals are firmly lodged in our throats."
W-e-e-e-l-l, I don't think that American forces will be that nice. From memory, they weren't in Vietnam. In fact, worrying about collateral damage in achieving (or failing to achieve) an objective has never appeared to be a major and high-priority component of American military procedure once the battle has started and the bullets, flamethrowers, iron bombs, chemical agents, napalm, air-fuel cells, shells, shrapnel and claymore mines have started flying. Unless, of course, there are TV cameras around.
