U.S. National Security Advisor Robert O’Brien will travel to Moscow to attend Russia’s World War Two Victory Day celebrations in May, U.S. ambassador John Sullivan said on Thursday. President Vladimir Putin presides over an annual parade on May 9 to commemorate the Soviet Union’s World War Two victory over Nazi Germany and uses the occasion to show off the country’s military hardware.
Relations between Russia and the United States are at post-Cold War lows, strained by everything from Russia’s detention on spying charges of a former U.S. Marine to U.S. allegations that Moscow meddled in its 2016 election. Russia invited U.S. President Donald Trump to attend the May 9 event, but he declined. U.S. officials said he had wanted to go, but faced pressure from his advisers not to.
