oh, please. i counted 43 attacks on americans by moslems in the name of islam since '89. we may not know all of them or those that were stopped. and several of them involved immigrants from the 7 named countries, or someone that had recently traveled to one. so 'bama passed this list of most dangerous nations on to trump. if people need additional vetting, so be it. isis did not exist when 911 occurred. we are playing a game with a global enemy, not just the warring factions of arab islam (been at it for 1200 years already!). build refugee camps on arab soil, have the UN support them (with the help of the arabs), and re-home them. wake up. grow up.
