Dear Prof,
they are somewhere under the ocean anywhere in the world and presumably undetectable.
Presumably, that's a good word, as technology quickens I can see a new game emerging, kids will be playing Pokemon on the bridge of our submarines.
The SDLP hit the nail on the head, this is a vanity project, we need to realise that we are no longer a super power, we also need to stop knee jerking to the U.S.A, the U.S.A can afford nuclear, we can't, time to step away from our alliance with America.
Time to say, we are British, we are not the poor cousins of America, time to step away from weapons of mass destruction and look at what we really need to function in this changing world, what we need is a fully functioning fully equipped Army, Navy and Air Force.
A Trident missile does not stop terrorism, terrorists laugh at Trident, in the full knowledge that we will never use it, it is a joke well past its sell date.
