text: Patrick J. Luby.  Hummm, maybe Trump mentioned Islamists because radical Islamists have chopped off American heads, kidnapped/raped/murdered Christians in their own countries, vowed "Death to America," and on and on.  Yes, some terrorists are homegrown.  Yes, some go to Muslim countries to get their terrorist training.  However, extreme vetting of immigrants/visitors from Islamic countries is a great start, not the complete solution.   In Islamic countries governed as theocracies, there is no separation between religion and state, quite the opposite.  BTW, it was Obama who devised the original list of countries, yet no one blinked at his proposal.  http://www.dailywire.com/news/11410/complete-list-radical-islamic-terror-attacks-us-james-barrett
