To those saying how will this radicalize those who weren't gonna be radicalized, think of it this way, in the past those terrorist groups had to do all the preaching on how the USA wants to destroy Muslim nations, and where once the leaders talked about this is not a war on islam, but on a few bad apples, now Trump is essentially saying this is about your religion, he's doing the preaching for the terrorist groups, telling them we do conquer your lands, support Israel taking your land, and don't want you in our pure Christian land.
This is the strongest evidence terrorist groups can use to recruit. Little Abdullah about to drop the koran and get his Rambo on after this shyt.
