Graham Allison is the Douglas Dillon Professor of Government at Harvard University where he has taught for five decades. Allison is a leading analyst of national security with special interests in nuclear weapons, Russia, China, and decision-making. Allison was the “Founding Dean” of Harvard’s John F. Kennedy School of Government, and until 2017, served as director of its Belfer Center for Science and International Affairs which is ranked the “#1 University Affiliated Think Tank” in the world. As Assistant Secretary of Defense in the first Clinton administration, Allison received the Defense Department’s highest civilian award, the Defense Medal for Distinguished Public Service, for “reshaping relations with Russia, Ukraine, Belarus, and Kazakhstan to reduce the former Soviet nuclear arsenal.” This resulted in the safe return of more than 12,000 tactical nuclear weapons from the former Soviet republics and the complete elimination of more than 4,000 strategic nuclear warheads previously targeted at the United States and left in Ukraine, Kazakhstan, and Belarus when the Soviet Union disappeared. Allison’s latest book, Destined for War: Can America and China Escape Thucydides’s Trap? (2017), is a national and international bestseller.
