Well, considering that in Afghanistan; they even let the Taliban into the Afghan Army, without knowing it,.......and that was supposedly under the supervision of American, British and other coalition forces........and those same infiltrators then shot countless numbers of coalition troops; I'd just love to know what vetting procedures will sort out the extremists, from among AT LEAST one and a half million refugees.......countless thousands of whom have deliberately thrown away their papers. The road to Hell is paved with good intentions and make no mistake.........Hell IS on the doorstep and knocking to come in.
