I don't understand the protests. I would expect educating Saudi youth in exceptionally liberal institutions like universities in the Northeast to have a net liberalizing effect on the Saudi government and culture long term. Is this not a better use of Saudi funds then e.g. buying more weapons?
The article points out that very few Saudi youth end up in America's best schools. The vast majority go to second-tier schools because their academic levels keep them from getting into the best schools.
The protests are about the elite institutions accepting funding from the Saudis, not students.
