This video is part of a special Council on Foreign Relations series that explores how 9/11 changed international relations and U.S. foreign policy. In this video, James M. Lindsay, Senior Vice President, Director of Studies, and Maurice R. Greenberg Chair at the Council on Foreign Relations traces the shifts in the balance of power in American politics following the terrorist attacks of Sept. 11, 2001. "What we witnessed in the months after the attack was a political dynamic as old as the American republic. When the country feels imperiled, the White House gains in power and Congress loses it," says Lindsay. However, ten years after the attacks, "the era of terrorism has given way to the era of fiscal austerity," Lindsay argues, and "we now have American politics that looks more normal, that is much more focused inward, and features much more heated battles between Capitol Hill and the White House."

Richard N. Haass argues that 9/11 was a terrible tragedy by any measure, but it was not a historical turning point that heralded a new era of international relations in which terrorists with a global agenda prevailed, or in which such spectacular terrorist attacks became commonplace.
