An expert on the dynamics of power in the post-Cold War world, Kagan writes extensively on domestic politics and U.S. strategy and diplomacy, including foreign policy, military strategy and the defense budget. His latest book, Of Paradise and Power: America and Europe in the New World Order, a New York Times and Washington Post bestseller, analyzes the historical causes of the gulf between European and American perspectives on power and the forces that seem to be inexorably widening the rift.

Kagan writes a monthly column in the Washington Post and is contributing editor to the Weekly Standard and the New Republic. He is the author of Twilight Struggle: American Power and Nicaragua, 1977-1990, and co-editor, with William Kristol, of Present Dangers: Crisis and Opportunity in American Foreign and Defense Policy.
