Former Mossad Chief Calls on Ahmadinejad to be Assassinated

Yes, the former chief of Mossad declared that:

"Ahmadinejad is the pusher of the entire Muslim world toward fanaticism and extremism. In his case, he should be made to disappear from the arena. He has said he wants to become a shahid, a martyr, so I think he should get his wish and be sent to heaven."

Isn't that advocating terrorism?? Does that mean that Meir Amit will be sent to Guantanamo? Of course not, he advocates 'good terrorism'.
