So he made a major policy decision on behalf of the US government and Israel committed an act of war because of it?

You are saying that Israel intends to treat him as a patriot and hero once he gets out. Makes sense, they want the next guy in his position to betray the US on Israels behalf. You are saying that is OK to betray your country for Israel. You are saying its just a calculated risk, that he should be punished the same as the guy who sold some secrets fro money. I say the fitting pubishment is the one that discourages the next person in his position from doing the same.

I say let him rot.
