When Rumsfeld isn't busy rearming a third world nation, which he helped create, even though the guns were stolen. His day involves the oversight over America's WMD proliferation prevention initiatives (Don't mention Saddam), the latest is called CONPLAN 8099. Which involves:

"Offensive operations, including potential conventional and nuclear attacks against WMD sites; elimination operations, in the event that offensive operations pose an “unacceptable risk” to civilians of U.S. and allied forces; interdiction of WMD materials during transport; WMD consequence management; cooperation with allies on WMD non-proliferation efforts; threat reduction work to eliminate WMD arsenals".

Perhaps a greater risk to the world is weapons of not so much destruction, support for oppressive regimes and arms dealing. Currently Somalia is gripped in a civil war between American backed warlords and the Islamic Tribunals. Although, the economic and military backed American side is loosing. What's considered a front in the war on terror is going wrong, and badly.
