Israel gets a few billion it can use to finance its "black ops" and hide from public scrutiny. And not to worry, in case the weapons should ever fall into the wrong hands, the Israelis have planted malware in the bombs code that will enable them to disable the bomb at any time, or to prevent the nuclear material from being used in a dirty bomb, they can cause a fizzle, and make a lot or terrorists "glow in the dark."...call it an industrial accident.
I love your theory/concept. I could see this cloak and dagger mission in a movie.
