The Russian government just announced its Avangard hypersonic missile to the world—intensifying the dispute about the future of U.S. arms control agreements with Moscow. The debate playing out among national security professionals, in the media and in select precincts of Congress is over whether to extend New START Treaty, a nuclear arms reduction agreement between the U.S. and Russia that was signed and ratified in 2010 and is up for renewal in 2021.
The problem with the squabble over the fate of New START, however, is that it assumes only two potential courses of action: either extend the treaty for five years unconditionally or allow it to expire in the hope of pursuing a more far reaching pact. Members of the disarmament community are pushing for the former option while some defense hawks have expressed interest in the latter.
