"I want to tell you that your fact sheet on the [Missile Technology Control Regime] is very well done and useful for me when I have to speak on MTCR issues."

Upholding the CTBT Regime in a Time of Adversity
Share this

As with other critical nuclear risk reduction and arms control agreements, the 1996 Comprehensive Nuclear Test Ban Treaty (CTBT) is under threat due to inattention, diplomatic inaction, and worsening relations between nuclear-armed adversaries.

Disturbingly, but not surprisingly, Russian President Vladimir Putin has signed a bill from the Russian parliament to “un-ratify” the CTBT, ostensibly to “mirror” the United States’ posture toward the treaty and somehow pressure the United States to ratify the pact.

Opening remarks from:

  • Dr. Robert Floyd, executive secretary of the CTBT Organization (CTBTO)

Followed by expert panelists:

  • Elena Chernenko, head of the international section at the Kommersant newspaper in Moscow, where she focuses on nonproliferation and arms control issues. She is also a member of the German-Russian-U.S. Experts Commission on Deep Cuts in nuclear arsenals.
  • María Antonieta Jáquez Huacuja, counselor, Secretariat of Foreign Affairs of Mexico, which is a co-sponsor of the resolution in support of the CTBT at the 78th UN General Assembly.
  • Daryl G. Kimball, executive director, Arms Control Association, veteran campaigner to end nuclear testing and advance the CTBT.
  • Shannon Bugos, senior policy analyst, Arms Control Association, moderator
