“Pollard is the only American ever to receive a life sentence for passing classified information to an ally of the U.S.[2]
In defense of his actions, Pollard declared that he committed espionage only because “the American intelligence establishment collectively endangered Israel’s security by withholding crucial information.”[3]”

So what? Israel then gave the information to the Russians.
Pollard should die in prison.
Not his call to make. He betrayed his country and OUR country and should rot to death in prison for it, if they're so dead-set on not hanging him.
