After Russia granted temporary asylum to former National Security Agency contractor and classified information leaker Edward Snowden, Obama canceled a summit in Moscow with Russian President Vladimir Putin. Obama complained on "The Tonight Show with Jay Leno" about Russia's "Cold War mentality." A few months later, with Obama unlikely to get congressional support for military action in Syria, Putin came to the rescue, offering an agreement to remove and destroy Syria's chemical weapons. Above: Putin, left, and Obama exchange words while meeting before the first session of the G20 summit in St. Petersburg, Russia, on Sept. 5.
