Israeli president Simon Peres allows that bombing Iran's nuclear facilities may not be the "best solution", because despite the extremely enjoyable violation of international law and the exciting opportunity to massacre hundreds of Untermenschen, "You cannot destroy the know-how to create centrifuges." But hey, that hasn't stopped them from trying:
Israel has launched a covert war against Iran as an alternative to direct military strikes against Tehran's nuclear programme, US intelligence sources have revealed.
It is using hitmen, sabotage, front companies and double agents to disrupt the regime's illicit weapons project, the experts say. [...]
Mossad was rumoured to be behind the death of Ardeshire Hassanpour, a top nuclear scientist at Iran's Isfahan uranium plant, who died in mysterious circumstances from reported "gas poisoning" in 2007.
Other recent deaths of important figures in the procurement and enrichment process in Iran and Europe have been the result of Israeli "hits", intended to deprive Tehran of key technical skills at the head of the programme, according to Western intelligence analysts.
"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."
There was no need for Peres to mention this, though, since I'm sure everyone here is already aware of it; after all, if a story had been published saying that Iranian hitmen were assassinating Israeli scientists and other officials it'd be all over the news here, right? And nobody could ever accuse the U.S. media or high government officials of double standards.
(As a fun mental exercise, try to imagine the circumference of the smoking-hole-that-used-to-be-Tehran if the Iranian government were in fact killing off Israelis this way.)
