Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments

April 1, 2019



This Report is transmitted pursuant to Section 403 of the Arms Control and Disarmament Act, as amended (22 U.S.C. 2593a), which requires a report by the President on Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments.


This Report assesses U.S. compliance with and adherence to arms control, nonproliferation, and disarmament agreements and related commitments in 2018, including Confidence- and Security-Building Measures (CSBMs), as well as the compliance and adherence in 2018 of other nations to arms control, nonproliferation, and disarmament agreements and commitments, including CSBMs and the Missile Technology Control Regime, to which the United States is a participating State. The issues addressed in this Report primarily reflect activities from January 1, 2018, through December 31, 2018, unless otherwise noted. 

The Compliance Report includes reporting and analysis at the levels of classification for which reliable supporting information is available. The longer unclassified version of this report, which will be submitted following full declassification review, recounts as much information as possible, but certain issues can be discussed only at higher levels of classification. Some compliance concerns are raised and some findings of violations are made, for instance, only in the TOP SECRET/SCI-level version of this Report. 


Arms control, nonproliferation, and disarmament agreements and related commitments continue to be important tools that can protect and advance U.S. interests. Their provisions can limit or reduce threats to U.S. and allies’ security, including by limiting participating States’ access to or engagement in dangerous or destabilizing capabilities or activities, providing insight and transparency into the actions of participating States, and encouraging stabilizing patterns of behavior and interaction. In these ways, such agreements and commitments can contribute broadly to transparency and stability on a global and regional scale.
