John Erath is the Senior Policy Director for the Center for Arms Control and Non-Proliferation, overseeing the policy team and guiding work on issues including Iran, Russia, North Korea, China, U.S. domestic nuclear policy and more. This follows 30 years of government service, much of it in arms control and non-proliferation.
Most recently, he completed a two-year assignment on the U.S. National Security Council, where he was responsible for European issues. In this capacity, he focused on cooperation with NATO and the European Union, as well as heading White House efforts to improve stability in the Balkans. He began his diplomatic career in the 1990s working in what was then Yugoslavia. He was later seconded to the OSCE in Kosovo and the Office of the High Representative in Sarajevo. Subsequently, he covered the Balkans at the U.S. Mission to NATO and for the Office of the Secretary of Defense.
In Washington, Erath also focused on arms control and non-proliferation, having worked on the delegation for adaptation of the Conventional Forces in Europe (CFE) Treaty and led the U.S. Delegation to the Wassenaar Arrangement General Working Group. He has also held diplomatic positions in India and Brazil. Until 2018, he headed the political-military affairs office at the U.S. Embassy in Ankara.
