On May 11, 2010, the Israeli Supreme Court ruled that Mordechai Vanunu, will "serve a three-month jail sentence handed to him by Jerusalem District Court and not community service. " 
The 'justices' refused Vanunu's offer to do community service in occupied east Jerusalem, because they do not view that side of town to be a part of their community.
On April 30, 2007, the Jerusalem Magistrate's Court, convicted Vanunu on 14 [out of 21] counts of violating a court order prohibiting him from speaking to foreign journalists in 2004. Vanunu was also convicted for traveling the four miles from Jerusalem to Bethlehem when he hoped to attend Christmas Eve mass at the Church of the Nativity, his first Christmas after being released from 18 years in jail [most of it in solitary] on April 21, 2004.
On July 2, 2007, Israel sentenced Vanunu to six more months in jail for speaking to foreign media in 2004.
On September 23, 2008, the Jerusalem District Court reduced Vanunu's sentence to three months, "In light of (Vanunu's) ailing health and the absence of claims that his actions put the country's security in jeopardy." 
On December 21, 2009, Uzi Eilam, an Israeli scientist, Tel Aviv University chemistry professor, former worker at Israel's Dimona reactor, former member of Israeli parliament, and the former head of Israel's Atomic Energy Commission told PRESS TV that Vanunu "served the regime because his revelations helped Tel Aviv intimidate others...I've always believed he should be let go. I don't think he has significant knowledge to reveal (about Dimona) now. "
On May 10, 2010, Uzi Even, spoke on Israeli army radio:
"The policy of nuclear ambiguity, by which we fool only ourselves and nobody else, is not good for us any more. It was good, effective and successful for close to 40 years, but over 40 years many things changed and now I am telling you clearly, this policy is no longer in our interest."
