Russia’s Duma voted on a bill to de-ratify the Comprehensive Nuclear-Test-Ban (CTBT) Treaty in the bill’s first reading in the State Duma on Tuesday.

Members of Russia’s State Duma unanimously adopted the bill withdrawing Russia from the CTBT. Chairman of the State Duma Vyacheslav Volodin said the Duma could consider the bill by October 19. Volodin mentioned that the United States has not ratified the CTBT for 23 years and further stated that the bill is a response to the United States’ “boorish attitude to its responsibilities in maintaining global security.” He shared that a US ambassador to Russia urged members of the State Duma not to support adoption of the bill on withdrawal of ratification of the CTBT.

Every member of the 412-person State Duma supported the withdrawal of Russia from the CTBT; there were no votes against the bill, nor were there abstentions. Volodin stated on his Telegram that the purpose of withdrawing was to “ensure the security of [Russia]” and to “ensure that global strategic parity is maintained.” Volodin has been ramping up attacks against the US in recent days. Last week, he called Washington the “main beneficiary of armed conflicts” and that Washington was “fomenting armed conflicts for its own enrichment.”

The CTBT was designed to end nuclear explosions and to promote nuclear disarmament. 44 States have ratified the treaty, including Russia. Eight countries have not ratified the treaty, including the US, China, Pakistan, India, Israel, Iran, Egypt, and North Korea.
