New York ? With President Barack Obama presiding, the U.N. Security Council on Thursday unanimously endorsed a sweeping strategy aimed at halting the spread of nuclear weapons and ultimately eliminating them, to usher in a world with “undiminished security for all.”

“That can be our destiny,” Obama declared after the 15-nation body adopted the historic, U.S.-initiated resolution at an unprecedented summit session. “We will leave this meeting with a renewed determination to achieve this shared goal.”

The lengthy document was aimed, in part, at the widely denounced nuclear programs of Iran and North Korea, although they were not named. It also reflected Obama’s ambitious agenda to embrace treaties and other agreements leading toward a nuclear weapon-free world, some of which is expected to encounter political opposition in Washington.

On both counts, Thursday’s 15-0 vote delivered a global consensus — countries ranging from Britain to China to Burkina Faso — that may add political impetus to dealing with nuclear violators, advancing arms control in international forums and winning support in the U.S. Congress.
