Straw man. I didn't say he didn't deserve punishment. The question is whether he deserved life in prison.
A better question is why the other spies you list didn't get life terms. Most on your list are obscure to the point that I couldn't find much information about their cases except at jonathanpollard.org. I did find this information about Marie Scranage where we learn that she cooperated with authorities to arrest another spy, her boyfriend Michael Soussoudis.
Were there any mitigating factors like that for Pollard? Isn't it the case that, rather than cooperating, he tried to flee arrest? What is the comparative damage done by Pollard's spying vs. Scranage and the others?
Other poster: YOU are the one who thinks Pollard's crimes weren't serious enough to warrant his punishment in the U.S. Federal justice system

Eh, "serious enough to warrant his punishment in the U.S. Federal justice system" is the same as "The question is whether he deserved life in prison", isn't it?
