WASHINGTON (AP) — The Obama administration is edging toward decisions that would further shrink the U.S. nuclear arsenal, possibly to between 1,000 and 1,100 warheads, reflecting new thinking on the role of nuclear weapons in an age of terror, say current and former officials.

The reductions that are under consideration align with President Barack Obama's vision of trimming the nation's nuclear arsenal without harming national security in the short term, and in the longer term, eliminating nuclear weapons.

The White House has yet to announce any plan for reducing the number of nuclear weapons, beyond commitments made in the recently completed New Start treaty with Russia, which obliges both countries to reduce their number of deployed long-range nuclear warheads to no more than 1,550 by 2018. As of March 1, Russia had already dropped its total to 1,492 and the U.S. stood at 1,737.
