The US withdrawal from the Anti-Ballistic Missile Treaty in 2002, followed by Russian violations and the subsequent US withdrawal from the Intermediate Nuclear Forces Treaty, have made the early 21st century a difficult period for arms control. The future of arms control, both for the strategic nuclear capabilities incorporated in New START and for non-strategic nuclear weapons is unclear. Moreover, emerging technologies like hypersonics and cyber assets, as well as the increasing militarization of space, are affecting the traditional arms control paradigm.
