Savings from scrapping Trident would be negligible
This is part of the
Guardian's coverage of the nuclear deterrent issue -which can be found
here.

There is no doubt that our biggest threat is from "stateless terrorist groups".
Isn't there?
I would suggest that Trident would have no deterrent effect at all on such groups and, as such, could not be financially justified.
But....
How many nuclear weapon states are there? Not many, which suggests that producing nuclear weapons is less than easy. A lot of scientific and industrial capability is needed. See this
FAS page.
Therefore, we could conclude that terrorists would find it hard to produce nuclear device without state sponsorship, which brings up the issue of deterrence.
