U.S. deficient against Muslim insurgents, study says

WASHINGTON (CNN) -- The U.S. military is seriously deficient in meeting "the threat of Islamist insurgencies," says a Pentagon-commissioned study released Monday.

The Rand Corp. report characterizes "U.S. military intervention and occupation in the Muslim world" as "at best inadequate, at worst counter-productive, and, on the whole, infeasible." The Pentagon asked the nonprofit research organization to review strategies to thwart insurgents.
