The ostensible purpose of your ban is to keep Americans safe from terrorists by barring visitors, refugees and immigrants from Iran, Libya, North Korea, Somalia, Syria, Venezuela and Yemen. So let’s consider, nonhysterically, what such a ban might have accomplished had it come into force in recent years.
It would not have barred Ramzi Yousef, the Kuwait-born Pakistani who helped mastermind the 1993 World Trade Center bombing.
It would have been irrelevant in the case of Terry Nichols and Timothy McVeigh, the American perpetrators of the 1995 Oklahoma City bombing in which 168 people were murdered.
It would have been irrelevant in the case of Eric Rudolph, the Christian terrorist who killed one person at the 1996 Atlanta Olympics and later bombed abortion clinics and a gay bar.
It would not have barred Mohamed Atta, ringleader of the 9/11 hijackers. Atta was an Egyptian citizen who arrived in the U.S. on a visa issued by the American Embassy in Berlin in May 2000.
It would not have barred Atta’s accomplices, all in the United States on legal visas. Fifteen of them were from Saudi Arabia, two from the United Arab Emirates and another from Lebanon.
It would have been irrelevant in the case of the 2001 anthrax attacks, in which five people were killed. The attacks are widely believed (without conclusive proof) to have been the work of the late Bruce Ivins, an American microbiologist.
It would not have barred Richard Reid, who tried to blow up a Miami-bound airliner in 2001 with explosives hidden in his shoes. Reid was a London-born Briton who converted to Islam as an adult.
