The last nuclear arms control treaty between the US and Russia is set to expire in February 2021, and talks between the two powers are not going well. Russia has offered to extend New START for five years with no preconditions, as the treaty allows, but the Trump administration is demanding concessions from Moscow.
Trump administration sources told The Washington Post that they were frustrated the Russians have not responded to a proposal submitted by US negotiators two weeks ago. Under the deal, the New START would be extended for a limited time, not the full five years, while the US and Russia negotiate a replacement treaty.
According to the Post, the proposal also said President Trump and Russian President Vladimir would sign a political agreement outlining a framework for the replacement treaty and what it would cover. The new framework the US is asking for is likely the reason Russia has not responded to it.
