"Israel has shown no hesitation in assassinating weapons scientists for hostile regimes in the past," said a European intelligence official, speaking on condition of anonymity. They did it with Iraq and they will do it with Iran when they can."
Mossad's covert operations cover a range of activities. The former CIA operative revealed how Israeli and US intelligence co-operated with European companies working in Iran to obtain photographs and other confidential material about Iranian nuclear and missile sites.
"It was a real company that operated from time to time in Iran and in the nature of their legitimate business came across information on various suspect Iranian facilities," he said.
Israel has also used front companies to infiltrate the Iranian purchasing network that the clerical regime uses to circumvent United Nations sanctions and obtain so-called "dual use" items – metals, valves, electronics, machinery – for its nuclear programme.
The businesses initially supply Iran with legitimate material, winning Tehran's trust, and then start to deliver faulty or defective items that "poison" the country's atomic activities.
"Without military strikes, there is still considerable scope for disrupting and damaging the Iranian programme and this has been done with some success," said Yossi Melman, a prominent Israeli journalist who covers security and intelligence issues for the Haaretz newspaper.
Mossad and Western intelligence operations have also infiltrated the Iranian nuclear programme and "bought" information from prominent atomic scientists. Israel has later selectively leaked some details to its allies, the media and United Nations atomic agency inspectors.
On one occasion, Iran itself is understood to have destroyed a nuclear facility near Tehran, bulldozing over the remains and replacing it with a football pitch, after its existence was revealed to UN inspectors. The regime feared that the discovery by inspectors of an undeclared nuclear facility would result in overwhelming pressure at the UN for tougher action against Iran.
The Iranian government has become so concerned about penetration of its programme that it has announced arrests of alleged spies in an attempt to discourage double agents. "Israel is part of a detailed and elaborate international effort to slow down the Iranian programme," said Mr Melman.
But Vince Canastraro, the former CIA counter-terrorism chief, expressed doubts about the efficacy of secret Israeli operations against Iran. "You cannot carry out foreign policy objectives via covert operations," he said. "You can't get rid of a couple of people and hope to affect Iran's nuclear capability."
Iran has consistently asserted that it is pursuing a nuclear capability for civilian energy generation purposes. But Israeli and Western intelligence agencies believe the 20-year-old programme, which was a secret until 2002, is designed to give the ruling mullahs an atom bomb.
