Sounds like a job for a MOAB. One look at a demonstration of that and they would beg to be taken prisoner. Or we could just use it and eliminate the risk... it would suck the air out of any nooks and crannies and pretty much get rid of even the roaches in that town. Since it's close to Syria I don't relish the idea of trying to play nice with all those wanna-be foreign jihadists that are probably there.
