Dr Hans Blix has urged Tony Blair to reconsider the UK’s future commitment to Trident nuclear weapons.

The chairman of The Weapons of Mass Destruction Commission believes that they are not necessary, that they have had their day, that we should be “walking away from it”.

I spoke to him at the end of a conference in Cambridge debating freedom of information, the use of political spin and, of course, that dodgy dossier and WMD. It was riveting stuff, but I was more interested in where the future lay.

We chatted afterwards over a glass of bubbly, Dr Blix is so incredibly affable and good humoured. He believes America is firmly entrenched in Iraq and will not withdraw its troops in the near future for fear of losing face, Bush will not want to appear the loser in the run up to the next presidential election in two years time, which makes good sense to me, though not a reason to be at war, he should be challenged about this motive.

But back to Trident and the future of WMDs. The peace loving Dr Blix and his Commission firmly believe we should be reducing our nuclear, biological and chemical weapons, South Africa is the only country to have walked away from them.

He believes we have “stagnated” regarding disarmament, and are rearming with Trident at a time when our warheads have almost halved from the peak of the cold war when they numbered 50,000 to 27,000 today. He said:

“I would like the UK to ask itself if they need them. I understand why Britain had nuclear weapons in the the first place, they were conventional weapons in those days. We are now working towards cooperation with Russia and Europe and detente, is it meaningful any more?”

Dr Blix’s recent WMD Commission report states that the world must aim at achieving a ban on both possession and use of nuclear weapons, in the same way as bans apply to biological and chemical weapons. All states – even the great powers – must prepare to live without nuclear weapons and other weapons of terror.

Which country will be the first to lay down its arms? Should we be supporting Trident or backing Dr Blix’s proposals? I would prefer a future without these weapons, but I would also like reassurance that this was happening globally. Is that a realistic expectation?
