UNITED NATIONS (AP) — The U.N. Security Council is set to vote Wednesday on a resolution sponsored by the United States and Japan calling on all nations to prevent a dangerous nuclear arms race in outer space. It is likely to be vetoed by Russia.

The resolution calls on all countries not to develop or deploy weapons of mass destruction, like nuclear arms, in space.

U.S. Ambassador Linda Thomas-Greenfield told a council meeting on March 18 where she announced the resolution that “any placement of nuclear weapons into orbit around the Earth would be unprecedented, dangerous and unacceptable.”

Russia’s deputy U.N. ambassador, Dmitry Polyansky, retorted that Moscow’s initial impression was that the resolution is “yet another propaganda stunt by Washington” and is “very politicized” and “divorced from reality.”

The announcement of the resolution followed White House confirmation in February that Russia has obtained a “troubling” anti-satellite weapon capability, although such a weapon is not operational yet.
