Milhollin is director the Wisconsin Project on Nuclear Arms Control, a non-profit research group in Washington, D.C. that has been tracking the spread of weapons of mass destruction since 1986. He will talk about who has nuclear weapons, who is developing them, who has intelligence about them and who poses the biggest threat. Milhollin is also professor Emeritus of the University of Wisconsin Law School. His op-ed pieces about nuclear weapons have appeared in many publications, including The New York Times.

His new book is The New Great Game. The book is about the battle over the world's largest reserve of untapped oil and gas resources, located in the Caspian Sea and surrounding Central Asian republics. The oil alone is said to be worth $4 trillion. Kleveman claims that the United States, China, Russia and Iran are now engaged in a power struggle for control of the region's vast reserves and pipeline routes. Lutz Kleveman was born in Germany and studied at the London School of Economics.
