The United States is the world's second largest nuclear power, coming close behind Russia. Together the two states account for 93 % of the world's nuclear weapons. Since the end of the Cold War, the US has followed a policy of reducing its nuclear arsenal, while maintaining a nuclear triad. Under President Obama, it embarked on an intense nuclear modernisation programme, while making commitments towards nuclear non-proliferation and – as a long-term goal – nuclear disarmament.

President Donald Trump took office in January 2017 with the promise to discontinue the previous administration's policy priorities. This is reflected in the current realignment of the US nuclear weapons policy. The new administration aims to expand US nuclear capabilities, is sceptical of international arms-control agreements, and has a more determinant stance on non-proliferation. President Trump has criticised the Joint Comprehensive Plan of Action (JCPOA), and consequently decertified the multilateral Iran nuclear deal in October 2017. The President has also characterised the bilateral New START Treaty, limiting the number of deployed strategic nuclear weapons between the US and Russia, as 'a one-sided deal'. The 1987 Intermediate-Range Nuclear Forces Treaty (INF Treaty), a landmark nuclear arms control treaty between the US and the former USSR, seems to be in limbo, and nuclear proliferation efforts in North Korea have sparked a war of words between Trump and the North Korean leader, Kim Jong-Un.

The ongoing Nuclear Posture Review, together with the coming passage of the annual defence policy bill in Congress, the National Defence Authorisation Act (NDAA) for 2018, have the potential to provoke shifts in US nuclear policy.
