Iraq was allegedly working on nuclear weapons, too: former President George W. Bush's famous "smoking gun", which also subsequently went missing.
On the basis of this "intelligence" about Iraq's "weapons of mass destruction," the US and its more gullible allies invaded the country. Hundreds of thousands died, no weapons were found, and nothing was learned. Here we go again.
Fool me once, shame on you. Fool me twice, shame on me. The same intelligence agencies are producing the same sort of reports about Iran that we heard eight years ago about Iraq's nuclear ambitions, and interpreting the information in the same highly prejudiced way.
Many people in the West realise they are being hustled into yet another attack on a Middle Eastern country, but they don't really worry about it too much. After all, it will only be air strikes, and we all know an air-only war is practically casualty-free for the side with air superiority. Look at Libya, for example.
But how many citizens of the US or Britain know Iran has 10 times as many people as Libya?
How many know Iran is a partially democratic, technologically proficient state with no history of attacking its neighbours, not a tinpot dictatorship run by a vicious loon? How many realise the war would not end with a few days of air strikes?
In Israel people do know those things and there is a vigorous debate about whether attacking Iran is a good idea.
A lot think it is not, and that also goes for both of Israel's intelligence agencies, Mossad and Shin Bet. Meir Dagan, the recently retired head of Mossad, said last January that an attack on Iran was "the stupidest idea".
So Israeli Prime Minister Benjamin Netanyahu and Defence Minister Ehud Barak, who both want to attack Iran (or rather, have the US do it for them), have gone public.
If the Western powers don't act at once, they warn, then Iran will get nuclear weapons and Armageddon will be just around the corner.
There are two things wrong with this proposition. One is the evidence. If you believe it all, it shows that Iran wants the knowledge and equipment that would let it build a nuclear weapon very quickly if necessary: an Israeli nuclear threat, a military coup in nuclear-armed Pakistan that brings young Shia-hating officers to power, whatever.
The evidence does not show that Iran is actually building a nuclear weapon, or has any intention of doing so. And having the knowledge and equipment that would let you do so fast in an emergency is entirely legal under IAEA rules.
The other problem with the accusations against Iran is the logic behind them. Building a nuclear weapon now would be extremely costly, not just in monetary terms. And it would be completely pointless as a deterrent if it remained secret.
Deterrence is the only logical reason that Iran would ever want nuclear weapons, since it would be suicidal for it to attack anybody with them. If Iran's leaders were completely logical in their thinking, they would rely on the fact that their military can completely shut the Gulf to oil traffic and bring the global economy to its knees if anybody attacks them.
In a recent exchange between French President Nicolas Sarkozy and US President Barack Obama that went out on an open microphone Sarko said: "I can't stand [Netanyahu] any more. He's a liar."
Obama replied: "YOU'RE sick of him? I have to deal with him every day." What about? One gets you 10 that it's about bombing Iran.
