- 1987 treaty has kept nuclear weapons out of Europe
- Trump announced withdrawal from deal with Russia in October
European officials are seeking to act as intermediaries between Russia and the US in the hope of salvaging a cold war-era arms control treaty that Donald Trump has threatened to scrap.
However, the diplomats involved are not confident of success in the effort to save the 1987 Intermediate-range Nuclear Forces (INF) treaty. Although they have the support of senior officials in the US defence and state departments, they face opposition from the White House, particularly from the national security adviser, John Bolton.
