By Karl Grossman, prof of journalism, Columbia Uni 28 April 2021 The U.S., the United Kingdom and the then Soviet Union joined decades ago in drafting the Outer Space Treaty of 1967 that designated space as a “global commons” for peaceful purposes. The treaty bans the deployment of weapons of mass destruction in space. It’s been signed by most nations on Earth. Russia and China—along with U.S. neighbor Canada—have led in a move to expand the Outer Space Treaty by outlawing the deployment of any weapons in space. PAROS has wide world support. But through a succession of U.S. administrations—Republican and Democrat—the U.S. government has voted against the PAROS treaty at the Conference on Disarmament of the United Nations. Because conference decisions must be supported by consensus, the U.S. has effectively vetoed enactment of the PAROS treaty.
