On Tuesday, the Liberal Democrat Conference will debate and vote on the future of Britain's nuclear weapons system. Putting this controversial issue out for open debate is much to the party's credit and its record on challenging the status quo on Trident is streets ahead of the two main Westminster parties, which remain mired in Cold war thinking.
Once again renewing Trident is in the news, so some time soon we can expect to hear politicians or commentators explain that Trident is necessary because off the threats from Iran or North Korea, or some other rogue regime. Unfortunately, this is a complete red herring of an argument as long as you've thought about the issue for a couple of minutes. And now I'm going to explain why.
The UK is currently at a crossroads: we can choose to become a world leader in disarmament, non-proliferation and the verification systems necessary to realise the eradication of nuclear weapons worldwide, or we can choose to contribute to global insecurity, nuclear proliferation, and increase the risk of nuclear terrorism through the modernising of our nuclear arsenal.
