The Washington Post reports:
U.S. military teams and intelligence agencies are deeply involved in secret joint operations with Yemeni troops who in the past six weeks have killed scores of people, among them six of 15 top leaders of a regional al-Qaeda affiliate, according to senior administration officials.
The operations, approved by President Obama and begun six weeks ago, involve several dozen troops from the U.S. military's clandestine Joint Special Operations Command (JSOC), whose main mission is tracking and killing suspected terrorists. The American advisers do not take part in raids in Yemen, but help plan missions, develop tactics and provide weapons and munitions. Highly sensitive intelligence is being shared with the Yemeni forces, including electronic and video surveillance, as well as three-dimensional terrain maps and detailed analysis of the al-Qaeda network.
This is, in rough outline, what George Will, Robert Pape and others had advocated for Afghanistan as an alternative to nation building. I guess we're going to get a real life experiment in which is the most effective.
