Pollard could not express remorse for his betrayal of the US. His reason: The US was committed to sharing intelligence with Israel but refuse to share it as freely as it did with Britain, for example. The US kept some secrets for itself. In fact, as the prosecutor demonstrated, Pollard could not have gone thru (physically) the mountain of documents he brought for copying by Israel. Pollard largely did not know the content. But he still felt justified in his actions. Most of the Jewish community felt embarrassed by the Pollard affair and kept quiet. But some spoke out in his favor, among them Rabbi Avi Weiss, and justified Pollard's action for the reason given above. The result was that Pollard could not fake remorse. I don't think the current AIPAC trial will help him get out soon.
