If Pollard, the government of Israel and the prominent Jewish groups do not back off then I am prepared to believe that Mr. Pollard has learned nothing from his incarceration, that potential spies have received no clear message of deterrance and that he should stay in prison until such time as he clearly renounces what he has done.

Just what "government of Israel and prominent Jewish groups" are you talking about? The lobbying on behalf of Pollard seems to be a largely grassroots effort in which those lobbying on his behalf are decrying the fact that prominent Jewish organizations and the Israeli government have not been involved in lobbying on behalf of Pollard.
