No, Gordon, you get real. Your argument about Trident being an insurance policy does not stack up. Nuclear deterrence is totally illogical.
We cannot afford the £100 billion cost of Trident - nor any substitutes. We need to save money. We have a huge budget deficit, remember?
Even cold warriors like Kissinger are calling for a nuclear-free world. The only place for Trident and the UK's non-independent nuclear WMD is on the negotiating table, on the way to a world 100% free of nuclear weapons.
