As Vanunu converted to Christianity, revealed the Nuclear Secrets 19 years ago he indeed risked ´many things. Let`s have a look to this quote:
"There are times when you have to obey a call which is the highest of all, i.e the voice of conscience even though such obedience may cost many a bitter tear, and even, separation from friends, from family, from the state to which you may belong, from all that you have held as dear as life itself."
Now he is breaking many of the restrictions, but I don`t think that those who know longer about the matter really think they will release him without any pressure of one our (until now)coward governments. MV said cooperation with the restriction is TO BE with the restrictions.
Ghandi: "no-cooperation is directed not against men but against measures. It is not directed against Governors, but against systems they administer. The roots of non-cooperation lie not in hatred, but in justice, if not in love."
Same for Refusikniks who are speaking out aloud what injustices are actually happening in the IDF(Israeli army). That means then actually: prison. Some people on the street want to even forbid them to think(if soldiers start to really think, well...)I admire them very much!!!
By the way Ghandi mentionned the quotes above on "fighting tyranny"!
