Graham 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 No. 1 university-affiliated think tank in the world. As assistant secretary of defense under President Clinton and special advisor to the secretary of defense under President Reagan, he has been a member of the secretary of defense’s advisory board for every secretary from Weinberger to Mattis. He has the sole distinction of having twice been awarded the Distinguished Public Service Medal, first by Secretary Cap Weinberger and second by Secretary Bill Perry. He has served on the advisory boards of the secretary of state, secretary of defense, and the director of the CIA. Dr. Allison’s latest book, Destined for War: Can America and China Escape Thucydides’s Trap? (2017), is a national and international bestseller.
