- No development of new warheads
- Change of attitude to nuclear engagement with a conventional attack no longer leading to nuclear reprisal
- Presumption against using nuclear weapons against non-nuclear countries
- Reduction in SDVs
- ICBMs reduced to carrying single warhead
There are a couple of disappointing points but by and large it's a step in the right direction. Interesting that the US is intending to just refurbish its nuclear weapons rather than build new ones while the UK is still ruminating about replacing Trident.
