Plans by Keir Starmer’s government to modernise and potentially expand Britain’s nuclear weapons arsenal, unveiled in the 2025 strategic defence review (SDR), seriously undermine international non-proliferation efforts. They will fuel a global nuclear arms race led by the US, China and Russia. And they increase the chances that lower-yield, so-called tactical nukes will be deployed and detonated in conflict zones.
This dangerous path leads in one direction only: towards the normalisation of nuclear warfare.
