Jack Dunphy’s great NRO piece today touches at the end on the issue of the border incursions, but there’s been a new development. A small southern California daily (whose reporters are all over immigration like white on rice) reports on an alert from the Department of Homeland Security that MS-13 is “planning coordinated attacks along the U.S. border with Mexico…against all law enforcement, to include Border Patrol” in order to “begin gaining control of areas, cities and regions within the U.S.” Whether this pans out or not, there’s no denying that the Mexican border is an increasingly dangerous security vulnerability, and can’t be addressed by the usual bromides and posturing.
