Not sure where I stand on the "hands tied behind their back", since I'm not a veteran I don't know if I have the right to have an opinion. But obviously you have to look at the BIG picture now, this isn't the WWII era. To garner support from allies, especially the MiddleEastern countries, instead of unilateral violent action, we have to use surgical strikes, and do what we can to avoid civilian casualties. YES IT SUCKS for our soldiers, but in the big picture, isn't that the better route, instead of dead civilians who are for the most part innocent, compared to the insurgents and extremists we really want to kill?
Otherwise yeah, we could just "nuke it into glass", right? Not a viable option.
