Russia plans to pull out of nuclear test ban treaty, envoy says

Russia has announced plans to revoke its ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). This decision comes after Russian President Vladimir Putin stated that Russia could consider revoking its ratification since the United States had signed but not ratified the treaty. The CTBT requires ratification from eight specific holdout countries, including the US, China, and North Korea, for it to enter into force.
