US prepared to spend Russia, China 'into oblivion' to win nuclear arms race: Envoy

US President Donald Trump's arms control negotiator on Thursday said the United States is prepared to spend Russia and China "into oblivion" in order to win a new nuclear arms race.

"The president has made clear that we have a tried and true practice here. We know how to win these races and we know how to spend the adversary into oblivion. If we have to, we will, but we sure would like to avoid it," Special Presidential Envoy Marshall Billingslea said in an online presentation to a Washington think tank.
