One nuclear strike will instantly wipe out millions of people, 99.999% of whom are civilians who had nothing to do with the conflict. As far as I see it, anyone who is willing to fire a nuclear weapon is nuts, inhumane, probably both. Therefore, they almost certainly wouldn't care about one coming back.
Let's say you're the leader of a country and you've just been told a nuclear weapon has wiped out one of your largest cities and a significant portion of your population. Would you retaliate by sending one back to the offending country to wipe out millions of their civilians, who were equally as uninvolved as your civilians? I would hope the answer is no...
So to sum up, I don't think Trident is a deterrent as anyone mad enough to use a nuclear weapon against any country wouldn't care about the consequences, and wouldn't be put off by the targets having nuclear weapons themselves.
Get rid.
Despite being in the Express, which makes it highly questionable, if true then this just reaffirms what I've said above. He's (apparently) ready to have nuclear war, and that's while we already have nuclear weapons. So what's the deterrent?
