Initially the Nixon Center, a Washington, D.C.-based public policy think tank. In March 2011, it was renamed The Center for the National Interest. The Center publishes the foreign policy bimonthly The National Interest (which it acquired in 2001) and tends to promote the realist perspective on foreign policy. The Center's President is Dimitri K. Simes.
The Center was established by former U.S. President Richard Nixon on January 20, 1994 as the Nixon Center for Peace and Freedom. The group changed its name to the Nixon Center in 1998. The center has a staff of approximately a dozen people supporting six main programs: Energy Security and Climate Change, Strategic Studies, US-Russia Relations, Immigration and National Security Studies, China Studies, and Regional Security (Middle East, Caspian Basin and South Asia). In 2006 it had an annual budget of $1.6 million. The Think Tanks and Civil Societies Program of the Foreign Policy Research Institute ranked it as one of the top 30 think tanks in the United States in 2007, and it has consistently earned similar praise since then.
