At over $840 billion, the United States Department of Defense budget request for 2024 accounts for ~3% of national income, almost half of all Federal discretionary budget outlays, and over 35% of global military spending. Michael E. O’Hanlon of the Brookings Institution joins EconoFact Chats to put these figures in historical context, and discuss how decisions about the size and type of defense expenditures the U.S. undertakes are made.

Michael is a Senior Fellow and the Director of Research in Foreign Policy at the Brookings Institution. He also serves as a member of the Defense Policy Board at the U.S. Department of Defense.
