I don't know what is going to be in the detail of this agreement. However, if it turns out that it limits offensive weapons, without a tie to defensive weapons. Then I don't welcome it at all. If you don't want war, then the way to prevent it, is to actually negotiate to reduce nuclear weapons, but preserve the deterrence. That means the whole focus of the agreement should be to preserve deterrence, not just to make lower numbers. If you just reduce and then the deterrent is eroded, then you will actually face an increased risk of the use of nuclear weapons. I would be happier with 2000 unused nuclear weapons than 1000 used weapons. The devil is in the detail on this one. We will in practice never give up our deterrence, so there will be a reaction if this agreement is wrong, and the US tries to takes advantage. Therefore in real terms this agreement is either making a more or less stable arrangement and hence a more or less likely lasting peace. Russia is a nuclear superpower and will always be, misguided adventurous attempts to try to change the balance won't work and in the end could lead to a catastrophic outcome for all the world.
