The voice may be stilled, but his combination of intellectual rigour and honesty, long since abandoned by our Prime Minister, stands as a reminder to those of us who sometimes doubt that the words "integrity" and "politician" can co-exist. DR MICHAEL WILKS LONDON SW1Sir: With the death of Robin Cook, those of us who opposed the Iraq war have lost a champion we can never replace, while the ever-fortunate Tony Blair has lost another thorn that constantly pricked him over Iraq. I always read with eagerness Robin Cook's comments on the subject in the newspapers. Tragically there are no anti-war speakers of the same calibre to take his place and counter the lickspittle MPs who voted for the Blair/Bush pact.PETE DAYDENABY, SOUTH YORKSHIRESir: Fine tributes from the Labour hierarchy are not a fitting response to the death of Robin Cook. He was a politician of principle who resigned from the government over its decision to take the country into the Iraq war.

There could be no more appropriate statement under these sad circumstances than one which indicated an intention to withdraw our troops from that country at the earliest opportunity.JIM MOOREWARWICKSir: Robin Cook will be remembered not only for his skillful diplomacy that helped to forge a political settlement of the Kosovo crisis, and for his opposition to the Iraq war, but also for his support for the Palestinian cause. His untimely death is a colossal loss for the Palestinian people because he was a staunch advocate of an indivisible and indissoluble Palestine who had struggled to bring our issue into the minds of people around the world.DR MUNJED FARID AL QUTOBLONDON NW2Sir: How saddened I am to hear about the death of Robin Cook. As soon as I saw his name at the top of a column, I knew I could expect irony, scepticism and intellectual bravado in his articles. He will be sorely missed.SARAH PEGGSEAFORD EAST SUSSEX The sad legacy of Hiroshima Sir: Thank you for such an illuminating piece about Hiroshima, and the awful legacy of the atomic bomb ("My God what have we done?", 5 August). It is hard to believe that 60 years on, the campaign to disarm is struggling to move forward.

As recent developments in Iran show, the debate between countries is characterised by suspicion, fear of the other, and brinkmanship, no doubt exacerbated by Bush's tendency to favour aggressive unilateralism over multilateral action and respect for international law.I attended the recent UN 30-year review talks of the nuclear Non-Proliferation Treaty (NPT) in New York. The Treaty binds the 184 non-nuclear states not to develop nuclear weapons providing that the five declared nuclear powers agree to multilateral disarmament I was staggered by the hypocrisy of the UK government. Ambassador to the UN, Sir Emyr Jones-Parry, told me he was proud of the UK's record on disarmament "Britain's record is the best in the world," he said. Only days earlier newspapers had reported Blair's decision to go ahead with replacing Trident, at a cost of anything up to £30bn.Scottish Greens are backing an international campaign to honour the victims of Hiroshima and Nagasaki by ridding the world of all nuclear weapons including depleted uranium by 2020. We need to let Blair know that British people shall not allow more weapons of mass destruction to be acquired in their name.CHRIS BALLANCE MSPSCOTTISH GREEN PARTYEDINBURGHSir: Hiroshima marked the 60th anniversary of the world's first atomic bombing with condemnation of a global trend toward nuclear proliferation. The wars and atrocities the US has perpetrated and the weapons it has developed are simply horrendous. America has been an agent of death and destruction in many third world nations, almost always leaving them in far worse shape than it found them.The U.S.
