I actually have personal knowledge and experience with this. From 2000-2003, I worked as an International Programs Manager at the Army HQ staff in charge of R&D cooperative agreements with Israel and other Middle Eastern countries. I traveled to Israel as part of a Department of Defense delegation in June 2001 to negotiate an MOU to jointly develop the Arrow 2 missile defense system.
But even though the program was 100 percent US funded, Israel refused to share the technology with us. I suspect that they later sold the technology to Communist China as they have done with most other advanced military technology we have shared with them.
With the new NDAA provision that was reported yesterday to integrate the US military with the IDF, we will end up transferring more advanced military technology with them than ever before and it will eventually end up in the PRC.
