Care to guess which nation has the highest number of US college alums serving in any foreign government cabinet in the world? http://www.businessinsider.com/does-it-matter-if-irans-leade...
Have you also measured the impact foreign students had on the institutions they attended? How many grants were given because of proposals from foreign students? How about how many US educated diplomats and/or foreign officials ended up improving their country's relations with the US because of their education experience?
Closest interaction I could find between him and US education institution was "Sheik Bakr Mohammed bin Laden, Osama bin Laden’s brother, made two gifts to the University in 1993 and 1994 to fund fellowships for advanced study in Islamic culture." ... "Harvard’s ties to bin Laden money have come into question before. In 1998, after Osama bin Laden was accused of the embassy bombings in Africa, then-University spokespeson Alex S. Huppé said, “It’s clear the Saudi bin Laden money is being put to good use here.”"
