America must not allow ANY U.S. Citizen to be murdered at the hands of terrorists without swift retaliation. There should be an immediate military response to this. ISIS is a plague that even the Pope can see, and everyday bleeding heart Americans plead for peace and diplomacy, these barbaric, murderous thugs continue murdering and raping kids and butchering adults. Hit them hard, hit them often and remove them from the face of the earth. Tax dollars well spent. By the way I am a veteran and have seen terror acts, so if you haven't been there don't bother with your bleeding heart responses. ISIS is a disease, a cancer that must be removed by the world.
