Barack Obama met Queen Elizabeth today, as protests turned violent on the streets of London. The leaders of 20 countries are preparing to meet on the global financial meltdown, and the eyes of the world are on the new President of the United States. Obama and Britain's Prime Minister Gordon Brown are calling for unified action, but France and Germany, Eastern Europe and the nations of Asia all have their own ideas. Can they agree on the need for economic stimulus, increased regulation or more money for the International Monetary Fund? Can Obama lead the way out of a crisis that started here and infected the rest of the world?
