According to Wikileaks there is much more too this story, involving Oil prices, military alliances and so forth with regards to Russia, the E.U. and India.
In the email, an Israeli intelligence source was asked about Defense Minister Ehud Barak's comment "the more the merrier" following the mysterious explosion that killed at least 17 people at an Iranian Revolutionary Guard Corps base near Tehran in November 2011. At the time, Iran claimed the blast was an accident, but US blogger Richard Silverstein said that Israel was the mastermind.
"I think this is a diversion. The Israelis already destroyed all the Iranian nuclear infrastructure on the ground weeks ago," said the Israeli source. "The current 'let's bomb Iran' campaign was ordered by the EU leaders to divert the public attention from their at home financial problems."....
Stratfor - the company who's email has been hacked said the following:
Some of the emails being published "may be forged or altered to include inaccuracies; some may be authentic," the company statement said.
According to the leaked emails, Europe and China would suffer from an Israeli attack on Iran (according to wikileaks) but that the Saudis and the Russians would benefit greatly. One can see the Saudi's but the Russians?
Again, this is an unverified report. HOWEVER, in any case it boxes Iran in a serious way. If they act on or accept this report, it means they acknowledge that they were indeed developing a nuclear weapon in a direct contradiction to their claims of the opposite. IF however, they deny this happened and that there was simply an attack on a Revolutionary Guard base then they are admitting to the world that Israeli and Kurdish forces were able to penetrate their most secure compound and wreck havoc. So much for their bellicose threats of retaliation, not too mention what message this sends to the Iranian People.

It will be interesting what Julian Assange says this afternoon when the documents are fully released.
