Center for Strategic and Budgetary Assessments
A think tank for national security and investment options, the Center for Strategic and Budgetary Assessments (CSBA) is an independent, non-partisan group. U.S. News and World Report called it "CSBA is one of those Washington, D.C., gems, a small, quiet research institute that, year after year, offers the public dependable, nonpartisan studies on military spending, with particularly valuable insights into the Pentagon's massive "black" budget–those classified programs with little oversight and often runaway spending."  Its staff and directors come from a wide range of viewpoints, from President Andrew Krepinevich to board members Jack Keane and R. James Woolsey.
