Sounds like somebody learned a hard lesson 50 or so years ago. Getting nuked sucks, but in the long run the nukees might benefit to the point where they send their best and brightest to US universities to learn something, rather than strapping a bomb on such promising individuals.
Saudi Arabia might take a lesson from this.
Saudi and other countries have done just what you've suggested, although not as you intended. Many of the scientists who were working on the nuclear, chemical, and biological weapons in Iraq were university educated in the US, UK, or other western countries. The same can be said for weapons scientists in many other threatening countries.
And let's not forget the "promising" Saudi citizens who came to the US to learn how to fly commercial airliners...
