Excuse me? The arms were shipped to Israel.
Israeli authorities believe that Israel was merely a transshipment point for delivery of the weapons systems to Iran.
ICE and Israeli authorities do not believe the final destination of Kohn’s shipments was Israel.
Israel already has access to the technology mentioned, it has no need to acquire these parts surrepticiously. This was a private arms dealer dealing with a third country, most likely Iran, from what I can see when I google his name.
