List of speakers

On August 29, at 11:00, the Valdai Discussion Club will host an expert discussion dedicated to the International Day Against Nuclear Tests.

Ten years ago, the United Nations declared August 29 the International Day Against Nuclear Tests. Since the 1950s, there have been approximately 2,000 nuclear tests, and history has shown how tragic and horrible their consequences can be. In 1996, the 50th session of the UN General Assembly adopted and submitted for signature the Comprehensive Nuclear-Test-Ban Treaty (CTBT). However, it never went into force, as many states which possess nuclear weapons, including the United States, China, India, and the DPRK, have not ratified it.

The limitations imposed on nuclear tests were of great importance during the Cold War, and they remain relevant now that the post-bipolar world order has collapsed. Now that the Intermediate-Range Nuclear Forces Treaty (the INF Treaty) has ceased to exist, the nuclear arms control system is no longer functional, giving countries new opportunities to develop nuclear weapons and conduct test launches. Additionally, contemporary nuclear weapons are much more powerful and destructive than those that existed 70 years ago.

On August 19, after abandoning the INF Treaty, the United States conducted a test of a new medium-range missile. The US military also confirmed that they are developing a hypersonic missile capable of carrying a ballistic warhead with a range that would have been prohibited under the arms control agreement. Due to this, the issue of the prohibition of nuclear tests is relevant as never before.

Will the CTBT ever enter into force? Is the prohibition of nuclear tests effective in countering the proliferation and improvement of nuclear weapons? Is a complete prohibition of nuclear tests and the elimination of nuclear arsenals possible? These and some other questions will be addressed by the participants of the expert discussion.
