The Tories have slipped up a bit with Trident. A couple of weeks ago they gave Faslane a long contract to keep thousands in work. This week they have come out and said that Corbyn is a national security issue as he wants to get rid of Trident. Reversing that statement, it is obvious that the UK will be ordering new Trident subs next year, even though they haven't read the report yet.
Anyway, regardless of the nukes, we need new Trident submarines. Subs proved how good they are in the Falklands.Plus we use them for launching cruise missiles.
As for the nukes, we only have a few of them, so we may as well keep them while other countries have them.
