It is interesting to note what happens to espionage cases in the United States. If you spy for China, or Cuba, or Iran you will be exposed, excoriated in the media, locked up and denied bail, convicted, and sentenced to many years in a federal prison.
Spies are traitors in every sense of the word, unless, of course, if one is spying for Israel.
Israel aggressively spies on the US both to influence policy and steal high technology, but getting caught only very rarely has any consequences. Leading neoconservatives like Richard Perle, Douglas Feith, and Stephen Bryen have all been detected in flagrante providing classified information to Israel but the investigations were halted and their security clearances were godfathered so they could continue to hold high office.FBI counter intelligence officer John Cole has reported on the frustration of his colleagues over the many cases of Israeli espionage that are dropped under orders from the Justice Department. He provides a "conservative estimate" of 125 worthwhile investigations into Israeli espionage in the US involving both American citizens and Israelis stopped due to political pressure from above. Israeli citizens and diplomats who are caught in the act spying are routinely freed without criminal charges and allowed to return home.
