The U.S. can’t afford to end its global leadership role (Ivo Daalder, Robert Kagan, Brookings)

The economic, political and security strategy that the United States has pursued for more than seven decades, under Democratic and Republican administrations alike, is today widely questioned by large segments of the American public and is under attack by leading political candidates in both parties. Many Americans no longer seem to value the liberal international order that the United States created after World War II and sustained throughout the Cold War and beyond. Or perhaps they take it for granted and have lost sight of the essential role the United States plays in supporting the international environment from which they benefit greatly. The unprecedented prosperity made possible by free and open markets and thriving international trade; the spread of democracy; and the avoidance of major conflict among great powers: All these remarkable accomplishments have depended on sustained U.S. engagement around the world. Yet politicians in both parties dangle before the public the vision of an America freed from the burdens of leadership.
