Robin Cooks "resignation speech" från det brittiska parlamentets "back benches" kommer att bli en retorisk klassiker:
" (...) For four years as foreign secretary I was partly responsible for the western strategy of containment.
Over the past decade that strategy destroyed more weapons than in the Gulf war, dismantled Iraq's nuclear weapons programme and halted Saddam's medium and long-range missiles programmes.
Iraq's military strength is now less than half its size than at the time of the last Gulf war.
Ironically, it is only because Iraq's military forces are so weak that we can even contemplate its invasion. Some advocates of conflict claim that Saddam's forces are so weak, so demoralised and so badly equipped that the war will be over in a few days.
Mrs Speaker, we cannot base our military strategy on the assumption that Saddam is weak and at the same time justify pre-emptive action on the claim that he is a threat.
Iraq probably has no weapons of mass destruction in the commonly understood sense of the term - namely a credible device capable of being delivered against a strategic city target.
It probably still has biological toxins and battlefield chemical munitions, but it has had them since the 1980s when US companies sold Saddam anthrax agents and the then British Government approved chemical and munitions factories.
Why is it now so urgent that we should take military action to disarm a military capacity that has been there for 20 years, and which we helped to create?
Why is it necessary to resort to war this week, while Saddam's ambition to complete his weapons programme is blocked by the presence of UN inspectors?
Only a couple of weeks ago, Hans Blix told the Security Council that the key remaining disarmament tasks could be completed within months.
I have heard it said that Iraq has had not months but 12 years in which to complete disarmament, and that our patience is exhausted.
Yet it is over 30 years since resolution 242 called on Israel to withdraw from the occupied territories.
We do not express the same impatience with the persistent refusal of Israel to comply.
I welcome the strong personal commitment that the prime minister has given to middle east peace, but Britain's positive role in the middle east does not redress the strong sense of injustice throughout the Muslim world at what they see as one rule for the allies of the US and another rule for the rest.
