You do realize that the Middle East is a huge fucking place right? And most of these people [ISIS etc] aren't just sitting around on a military base. They're spread out, often among civilian population.
So you know, why not just commit massive atrocities in the name of hoping to wipe out a few thousand extremists. Good plan. Do exactly what they're doing on a larger scale... cause that won't make the US look like massive hypocrites or anything... Oh wait. They already do.
Master strategist right here.
