Temporarily Banning Islamic Immigration; Politically Incorrect Or A Matter Of Security?

Donald J. Trump is calling for a total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what is going on. Is this a smart security move or is it just plain politically incorrect as most on the left and the right have spent the last 2 days pontificating? Trump's comments have been called un-American, racist and bigoted. However, if radical Islamist extremists are calling for the destruction of the West, should we not be reviewing our immigration policies that are actually legally allowing radicals into our country? Tashfeen Malik, the San Bernadino terrorist, entered into the United States on a "fiancee" visa in July of 2014, even though later investigations into her background revealed glaring red flags. Some left leaning publications, like the Huffington Post, suggest that terrorists gaining access through the refugee path is highly unlikely, however, the facts remain a stubborn thing. We know that at least one of the Paris terrorists who killed over 120 people actually entered into the country as a Syrian refugee while two others carried false Turkish passports.
