Vladimir Putin’s public speech Thursday night hit many of its objectives: a memorable branding moment for a politician heading into an election this month, boasted a new image of Russia after years of economic stagnation and military decline, and debuted a shiny new missile to emphasize that point.

The new nuclear‐​powered cruise missile could have serious implications for U.S.-Russia relations by complicating the bilateral New START treaty that intended to downsize the world’s two largest nuclear arsenals. The state of American nonproliferation efforts seems to be at a low in recent history. President Trump frequently threatens to rip up the Iran Nuclear Deal and antagonizes North Korea, another rogue nuclear power. Hopefully policymakers can resist using this new Russian missile as an excuse to undercut New START and cease advocating for nonproliferation on the global stage.
