Is North Korea's testing of nuclear weapons a reason for Britain holding on to its nuclear deterrent? The southeast Asian dictatorship announced today that it had carried out its second ever nuclear test — in direct contravention of an international ban. US President Barack Obama has described the action as a "threat to international peace" and Britain's Prime Minister Gordon Brown said he condemned the test "in the strongest terms". But with 64 Trident missiles stationed on the Clyde alone — and a commitment to renew these nuclear warheads — are we guilty of hypocrisy? Or does an increasing threat from "rogue" states mean we should be hanging on to our military deterrents? Graham Stewart takes your calls, texts and emails.
