You can't halve the submarine count to two. It would make them vulnerable to attack, due to dy dock time. We already only have enough to maintain one at sea permantley.
Without nukes your fear of conventional weapons would grow massively, as there's little deterent for skirmish poping up even more than they currently do.
The trident doesn't need reallocating for other stuff, we need to get our finances under control, NHS and benefits are the two massive culprits. Then I would say waste, part instutional, 1mangaer for 1 employee. What my mate just got in MOD. How the hell do you manage one person It's insane. Must be a cushy job though, then partly over complicated systems and crap contracts with lack of penalties. Goverment IT systems are a good example.
Whilst sorting out those issues, we need to insure our future income, the uk has always been cutting edge technology, we are not set up to fund this properly and then reap the benefits.
I never said anything about conventional weapons, I meant smaller nuclear weapons, while i doubt our borders are that unprotected, i wont bother assuming otherwise, either way if you say 2 is not enough, then fine, I did not know, I don't really wish to become so orientated in dock times.
I haven't even gone into the usual problems in the MoD costing something, then somehow it comes out 10 times more costly, but that may not occur, so isn't really a point.
I haven't even gone into potential problems with European breakdown yet, but its late and i suppose i don't really want to.
I suppose having them is equally as crap as not having them, I do try to have an idealistic view, "a better world" and such, but i am somewhat a destructive person and indeed find nuclear explosions impressively curious, but i find it rather reprehensible, so i must try to attack these objects consistently.
