The Washington Post is reporting the Trump administration recently discussed conducting the first U.S. nuclear test explosion since 1992. One official told the paper the test could help the U.S. in nuclear negotiations with Russia and China. But Daryl Kimball of the Arms Control Association warned the move “would be the starting gun to an unprecedented nuclear arms race.” Last week, the Trump administration announced it is withdrawing from the Open Skies Treaty, a major international arms control deal. Last year, Trump also withdrew from the INF Treaty — the Intermediate-Range Nuclear Forces Treaty with Russia.
