Should U.S. Missile Defenses Be a Part of Arms Control Negotiations With Russia? The Biden administration should consider whether the benefits to United States and allied security of limiting all nuclear weapons, including non-strategic nuclear arms, would justify accepting some constraints on missile defense. A consensus has grown in Washington that the next nuclear arms negotiation with Moscow should aim to limit all U.S. and Russian nuclear weapons, not just deployed strategic ones. That would raise challenging issues. Moscow may insist that it would put non-strategic weapons on the table only if Washington addresses issues of concern to Russia, particularly, missile defense.
