Dr. Allison has served as Special Advisor to the Secretary of Defense under President Reagan. He received his A.B. from Harvard University, his M.A. from Oxford University, and his PhD from Harvard University. Dr. Allison's first book, Essence of Decision: Explaining the Cuban Missile Crisis (1971), was released in an updated and revised second edition (1999) and ranks among the bestsellers in 20th century political science with more than 400,000 copies in print.
