Leaders of the world's largest economies are proclaiming success for their G-20 summit, promising concerted action against the global recession. The US and Britain say they got what they wanted.

For President Obama, it's on to the 60th anniversary of NATO. What's the modern role of history's most successful alliance? How much help will the US get in Afghanistan? Will NATO expansion continue in the direction of Russia?
