The UK's nuclear deterrent should be scrapped, according to a group of retired senior military officers. General Lord Ramsbotham and Field Marshal Lord Bramall have written a letter to The Times denouncing Trident, saying the system is "irrelevant". They argue that rather than spending Â£20bn renewing the scheme, more funds should be spent on the armed forces. Supporters say it is still essential that the UK should maintain its independent nuclear arsenal. In the letter, which is to be published in The Times on Friday, the men say the UK is too dependent on the US when it comes to defence. They write: "Nuclear weapons have shown themselves to be completely useless as a deterrent to the threats and scale of the violence we currently face, or are likely to face - particularly international terrorism." john I have said this for years.
