Trump's call for U.S. nuclear supremacy raises questions

“I know of no senior American military officer who says ‘I would like to trade American nuclear forces with anybody else,'” said Steven Pifer, director of arms control and nonproliferation at the Brookings Institution, who said he and other experts are “just not sure where Trump’s getting his information.”…

Experts — and critics — say no country can match the US for the strength, size or modernity of its nuclear weaponry.

In a January 2017 speech, Vice President Joe Biden said that as of September 30, 2016, the US possessed 4,018 active and inactive nuclear warheads and about 2,800 more warheads that were retired and awaiting dismantlement.

In September, under declarations required by the New Strategic Arms Reduction Treaty (START), Russia said it had 1,796 strategic warheads deployed on submarines, missiles and bombers. The Federation of American Scientists estimates Moscow has another 2,700 warheads — both more powerful warheads that aren’t deployed and smaller ones. The FAS estimates that Russia has another 2,510 warheads in line to be dismantled.
