How exactly is sending Vanunu back to jail for a vaiolation of his parol based on revenge? Are you saying that in your country criminals out on parol don't get sent back to jail if they break the terms of their release? Vanunu was even given the offer of community service in west Jerusalem rather than jail but he said he prefered jail to community service working in jewish areas. What he did when he told the world about Israels nuclear program was illegal and I think in the majority of countries actions like that would be considered illegal and he went to jail for breaking the law. Just because you see Vanunu as some kind of hero doesn't mean that locking him up after he went public and locking him up again now for violation of parol is based on a childish idea of revenge its based on THE RULE OF LAW. Society needs laws and just because you think that somebody is a hero because they broke the law doesn't make it justified or that they should be exempt from punishment.
