Enhancing U.S. Preventive Actionprovides an actionable road map for how the U.S. government should revamp its existing prevention architecture to make it more effective in dealing with potential crises abroad. Paul B. Stares and Micah Zenko analyze the shortcomings of the prevention capacities within the U.S. government. They provide concrete recommendations for creating new interagency coordinating mechanisms within the National Security Council, improving the delivery of useful and timely early warning mechanisms to policymakers, and strengthening the unique institutional capabilities within the U.S. Agency for International Development and the State Department.
