Robert Lieber, professor of government and international affairs, on President Obama using his popularity to create positive foreign policy changes:

"The crucial but as yet unanswered question is this: To what extent is the surge in favorability translatable into foreign-policy actions that serve U.S. interests, answer global challenges, and meet the security threats we and our allies face? We're still early in the game at only eight months into this presidency, but so far, any tangible gains are yet to be seen."
