The One’s mea culpa to the world:

The President opened a town-hall style gathering with the declaration, saying he would outline details in Prague in the coming days.

He said: “Even with the Cold War now over, the spread of nuclear weapons or the theft of nuclear material could lead to the extermination of any city on the planet.”

Mr Obama said that the US shares blame for the crisis, but that “every nation bears responsibility for what lies ahead - especially now”.

He added: “I’ve come to Europe this week to renew our partnership. America is changing but it cannot be America alone that changes.”

This little tidbit was tucked neatly into an article about Sarkozy’s wife refusing to kiss Obama. She clearly has the better judgment.
