Despite challenges, US-Russian nuclear arms control has its benefits

The last treaty limiting US and Russian nuclear arsenals, known as New START, expires in less than four years, which is not much time to put into place a replacement arms control arrangement. With bilateral tensions soaring, particularly given Russia's invasion of Ukraine, Washington and Moscow must hold formal negotiations on a New START follow-on arrangement sooner rather than later, so as to prevent miscalculation or escalation - and ensure strategic stability between the world's two largest owners of nuclear weapons. The negotiations rely on strong political will from both sides, who will each bring to the table a different agenda requiring some concessions from the other. Divisive though the talks will inevitably be, the United States and Russia can reach agreement on crucial issues of concern, such as Russia's new nuclear weapon delivery systems unveiled in 2018 and 2019.
