Scott Shane in NYT on the irrationality of Trump's executive order:

'While the order requires the Department of Homeland Security to issue a report within 180 days providing detailed statistics on foreign nationals who commit acts of violence, terrorism researchers have already produced rich and revealing data. For instance, since the terrorist attacks of Sept. 11, 2001, no one has been killed in the United States in a terrorist attack by anyone who emigrated from or whose parents emigrated from Syria, Iraq, Iran, Libya, Somalia, Sudan and Yemen, the seven countries targeted in the order’s 120-day visa ban, according to Charles Kurzman, a sociology professor at the University of North Carolina.'

'There was a random quality to the list of countries: It excluded Saudi Arabia and Egypt, where the founders of Al Qaeda and many other jihadist groups have originated. Also excluded are Pakistan and Afghanistan, where persistent extremism and decades of war have produced militants who have occasionally reached the United States. Notably, perhaps, the list avoided Muslim countries where Mr. Trump has major business ventures.'

(...)

'By Mr. Kurzman’s count, 123 people have been killed in the United States by Muslim terrorists since the 2001 attacks — out of a total of more than 230,000 killings, by gang members, drug dealers, angry spouses, white supremacists, psychopaths, drunks and people of every description. So the order addresses, at most, one-1,870th of the problem of lethal violence in America. If the toll of Sept. 11 is included, jihadists still account for just over 1 percent of killings.'

'"In my opinion, this is just a huge mistake in terms of counterterrorism cooperation,” said Daniel Benjamin, formerly the State Department’s top counterterrorism official and now a scholar at Dartmouth. “For the life of me, I don’t see why we would want to alienate the Iraqis when they are the ground force against ISIS.”'

What's sold as counterterrorism measures is not only highly unethical, it will turn out to be a boost for those groups who the President of the US claims he wants to destroy.
