Nuclear arms hawks give bureaucratic mauling to Biden vow to curb arsenal

Defence budget and nuclear posture review are battlegrounds as Republicans seek to block limits on US use of weapons

A battle is being fought in Washington over the Biden administration's nuclear weapons policy, amid fears by arms control advocates that the president will renege on campaign promises to rein in the US arsenal.

The battlegrounds are a nuclear posture review (NPR) due early next year and a defence budget expected about the same time. At stake is a chance to put the brakes on an arms race between the US, Russia and China - or the risk of that race accelerating.
