Nicolas Sarkozy, the French president, came close to mocking his American counterpart for the good intentions, which Mr Obama had heralded as an "historic" step towards nuclear abolition, even though it set no specific targets or fresh mandates.
"We live in a real world not a virtual world," the Frenchman told the 15-member council. "And the real world expects us to take decisions.
"President Obama dreams of a world without weapons ... but right in front of us two countries are doing the exact opposite.
"Iran since 2005 has flouted five security council resolutions. North Korea has been defying council resolutions since 1993.
"I support the extended hand of the Americans, but what good has proposals for dialogue brought the international community?
Oh, the shame of having a Frenchman be more realistic than the American president.
