Obama pointed to negotiations between Washington and Moscow that are leading to the most sweeping arms control treaty in nearly two decades.

And he looked ahead to an April summit of 44 nations aimed at securing nuclear materials all over the world.

Obama says the international community is now more united against the spread of these weapons _ bringing more isolation to North Korea and Iran.
