the world is a very different place then when 911 happened. we have seen the rise of ISIS, a self-declared global caliphate. and if you don't know what that means, study it. the 7 countries have nothing to do with Trump's businesses- that is more of the globalist-leftist lies. Trump inherited 8 years of bama/billary's bungling. they took out libya, took out egypt, meddled in the ukraine, and took us in to Yemen and Syria. these are religious wars, folks. these people have been fighting since the beginning of islam. should we pull out and come home? i think we need to let the moslems fight themselves out. rebuild america. we don't have to take everyone in, nor can we. let the arabs build camps, on their lands, and re-home the people. it is their problem, not ours. the UN can help feed them. history and current events in a studied manner without PC is sorely missing in this (once great) nation. several times presidents have banned immigrants. not a bad thing.
