Yes. In the USA there is draft legislation in both the House of Representatives and the Senate to enshrine no-first-use into US law. President Biden has indicated support for at least sole purpose, if not no-first-use. The Parliamentary Assembly of the Organization for Security and Cooperation in Europe (which comprises the legislatures of France, Russia, UK, USA and all the European and former Soviet countries) has adopted resolutions supporting no-first-use. This has given rise to new momentum amongst civil society, especially in the US, to advance no-first-use policies.
