Let’s try this one more time and maybe you can understand. Allies spy on each other. South Korea spies on us, Taiwan spies on us and Israel spied on us. Frankly I can understand why those nations do since to varying degrees their survival is in the balance and it is vital for them to know what we are doing that may affect their survival.
Now do I condone Americans who help them for reasons of money or ideology? The answer is no, I say they should be prosecuted as Pollard was. Do I think what they did is less serious than spying for an enemy? Yes, it is obvious and if you cannot grasp that concept, I probably cannot help you. Just as we don’t have a death penalty for assaulting someone, while we do consider it a serious crime it is not in the same class as murder. We have intermediate punishments for less serious crimes.
You may not like that fact but it is a fact. And we have accepted it as a society in the practice of sentencing those who have spied for allies much less seriously than those who spied for enemies. Pollard is a lone exception as has been demonstrated. Do you feel all the others should have been sentenced much more harshly? Perhaps you do. Curiously you only mention Pollard but never complain about all those others who served two years or less for spying for allies.
We're not exactly at war with Russia. Have you checked the sentence given to Robert Hannsen?
