Target: New York

Another terror attack in America’s biggest city reminds us of the ongoing threat—and the problems with U.S. immigration policy.

Two attacks on Manhattan in the last six weeks by ISIS-inspired terrorists demonstrate that the jihadi threat is serious and real. Sayfullo Saipov, the Uzbeki national who murdered eight people with a truck on Halloween, and Akayed Ullah, the Bangladeshi whose pipe bomb appears to have detonated prematurely in the subway system this morning, are adherents of a radical ideology that urges armed struggle against the West. They’re also recent immigrants to the United States, each arriving around 2010 from their respective countries.
