This argument makes no sense. Should an American who spied for Hitler have been freed and forgiven because the Third Reich ultimately fell?

30 years later, maybe. It depends. What specifically did he do for the Third Reich? Out US agents? Sabotage US ships? Reveal battle plans causing major reversals with ships sunk and servicemen killed? Or just tell the Nazis, during nominally peaceful times (before Pearl Harbor, to work within the confines of your analogy) how the US Navy manages to keep track of their nuclear subs, causing the US to do more R&D to find a new way? The latter is what Pollard did for the Soviets. At the same time, he also made sure that Begin’s Israel had enough information to take out Saddam Hussein’s Iraqi nuclear program, saving perhaps millions of lives, both American, Israeli, and Arab. The first deed was dastardly enough. The second, however, more than compensated for the damage he did with the first.
