The U.N. Security Council is set to vote on a resolution calling on all nations to prevent a dangerous nuclear arms race in outer space. It is sponsored by the United States and Japan and likely to be vetoed by Russia. The resolution facing a vote Wednesday calls on all countries not to develop or deploy weapons of mass destruction in space. U.S. Ambassador Linda Thomas-Greenfield told a council meeting last month where she announced the resolution that this would be “unprecedented, dangerous and unacceptable.” Russia’s deputy U.N. ambassador retorted that Moscow’s initial impression was that the resolution is “yet another propaganda stunt by Washington."
