Perry and former national security adviser Brent Scowcroft, an independent task force takes a fresh look at current U.S. nuclear doctrine and policy and determines the underlying purpose of America's nuclear weapons. Their report outlines a strategy for achieving the fundamental objectives of U.S. nuclear weapons through the skillful management of important political relationships and relevant amendments to policies on nonproliferation, arms control, nuclear terrorism prevention, securing nuclear weapons and weapons-usable materials, and ensuring crisis stability.
