Seems to me Israel and South Africa were stealing krytrons back in the 1970's. Read about krytrons in Wikipedia. They don't seem all that difficult to understand. Why doesn't someone make knockoffs in China and sell them legally? That way, the US is not involved and I don't have to read about how Jonathan Pollard is such a hero. He may be a hero to Israel, but the ONLY reason he is not STILL spying for Israel today is that he was an obnoxious jerk and his boss wanted to fire him. His boss knew he was taking home secrets but never would have launched a formal investigation if Pollard had been a helpful and quiet employee instead of a disruptive narcissist. Once the investigation started, Pollard was done. Google Irit Erb.
