Haaretz: 'Iran hates al Jubeir because he is the Saudi "envoy" to the US Jewish community'

"...  Very few details were published about the military plan, but those that were published showed the plan was inadequate and amateurish. This created a lack of trust in the American announcement. Specialists on Iran – most of whom frequent Gary Sick's Internet forum, the Gulf/2000 Project – hastened to support Iran and raise doubts as to whether it was really behind the plot. Others went so far as to weave conspiracy theories that the American government, with the support of its intelligence, fabricated the operation to incriminate Iran,... There were even those who conjured conspiracy theories in their sick minds that blame the Mossad for being behind the act in order to provoke a war between Washington and Tehran. In this context, they reminded that Israel played an important role in gathering "evidence" against Sudam Hussein's regime in Iraq in order to push the U.S. to invade Iraq. But even without these conspiracy theories, the Americans and the world remember that George W. Bush used faulty intelligence information to show Sudam Hussein was developing nuclear weapons – or at least chemical and biological weapons – as a justification for invading Iraq in 2003. If the Israeli intelligence, many in the U.S. claim, was capable of using the information and intelligence assessments for political echelon, who could guarantee they wouldn't do it again?...
The charges do not mention the plot to attack the Israeli embassies, but it was reported in the American and Argentinean media and was based on conversations with government officials....  
It's hard to believe that Iran, who has significant intelligence capabilities and has carried out sophisticated terror attacks in the past – would assign such an important task to an Iranian-American whose favorite drink is whiskey....
The Saudis also believe the Iranian plot is real. Saudi Foreign Minister Saud al-Faisal said last week in a visit to Austria that "we hold (the Iranians) responsible for any action they take against us." He indicated that this is not the first time Iran is suspected of such operations.Yet one must not forget that Iran's Quds Force and intelligence agency are responsible for various terrorist operations in recent decades, which were carried out by Iranian, Lebanese, or other dissidents....
Furthermore, Saudi Arabia's ambassador Adel Al-Jubeir is considered a bitter rival of Iran (because 'others' in the Saudi government are not?) and his actions have been loathed by the Ayatollah regime for years. He is a seasoned diplomat ... and according to WikiLeaks documents he was one of the people who succeeded in toughening the king's stance toward Iran. Moreover, before being appointed ambassador he was considered an "envoy" to the Jewish community in the U.S. – meeting Jewish leaders and bringing about a certain change in the embassy's traditionally hostile stance towards the Jewish community. There is no chance that the last weapons deal between Saudi Arabia and the U.S. went through almost without opposition in Congress. One of the reasons for this was that the pro-Israeli lobby AIPAC didn't oppose it.
With such a record, the Saudi ambassador could definitely constitute a fitting target..."
