US President Donald Trump has called for a new treaty following the expiration of the New START nuclear arms control treaty with Russia.
Trump said in a social media post on Thursday that rather than extend New START, "we should have our Nuclear Experts work on a new, improved, and modernized Treaty that can last long into the future."
Russian President Vladimir Putin effectively proposed last September extending New START by another year. But no agreement was reached with the United States, and the treaty expired on Thursday.
