CTBTO chief lauds drop in nuke tests in 30 yrs since UN adoption

The head of the Comprehensive Nuclear Test Ban Treaty Organization, Robert Floyd, expressed satisfaction on Tuesday with the significant decline in nuclear weapon explosive tests over the past three decades since the treaty's adoption by the United Nations in 1996. Floyd noted that prior to the treaty, more than 2,000 nuclear tests were conducted, but that number has plummeted to less than a dozen, with North Korea being the sole country still conducting such tests.

Floyd emphasized that the reduction of nuclear tests has brought about a genuine peace and security benefit for the entire world. However, the Comprehensive Nuclear Test Ban Treaty (CTBT) is not yet in effect, as the treaty requires ratification from all five major nuclear states - the United States, China, Russia, the United Kingdom, and France. Currently, the United States and China have signed but not ratified the treaty, while Russia withdrew its ratification in 2023.

According to Floyd, the absence of simultaneous ratifications by the United States and China makes the treaty ineffective. He believes that Russia and other countries that have not ratified the treaty would join them if the U.S. and China were to do so concurrently. Floyd highlighted the importance of the organization's International Monitoring System, which consists of 308 monitoring stations and laboratories worldwide, designed to detect nuclear tests.

He stressed that the data from these stations is shared with the International Data Center in Vienna, ensuring global transparency and discouraging potential nuclear tests.

While acknowledging the potential advancements in artificial intelligence for detecting even smaller-scale nuclear tests, Floyd maintained that human analysts will continue to interpret the data. He praised Japan's deep commitment to the organization, alongside Australia, as founding members of the Friends of the CTBT group in 2002.

Over the years, the group has held 12 meetings to support the treaty's implementation. Floyd argued that the CTBTO plays a crucial role in preventing new types of nuclear weapons by nuclear-armed states and stressed the importance of the organization's role in building a world free of nuclear weapons.
