Russia warned Wednesday it is prepared to build a new generation of nuclear-capable missiles if the U.S. deploys similar weapons in Europe. This is Russia’s deputy representative for disarmament speaking at a United Nations forum in Geneva on Wednesday.

Alexander Deyneko: “What is important here is that in its tactical and technical features, in particular the flight time from the command center, our weapons would correspond to the threat directed against Russia. We know how to do this, and we would implement these plans immediately, as soon as such a threat would become a reality.”

This month, the Trump administration formally announced it is withdrawing from the Intermediate-Range Nuclear Forces Treaty—the INF—the landmark 1987 treaty banning all nuclear and non-nuclear missiles with short and medium ranges, negotiated between Reagan and Gorbachev.
