From this post at Islam in Action, citing this source:
...Fareed Zakaria, editor of Newsweek International, a world affairs columnist and CNN host who serves on Yale's governing board, said he told Yale that he believed publishing the images would have provoked violence.It appears that BHO had Zakaria's book The Post-American World on his reading list:
"As a journalist and public commentator, I believe deeply in the First Amendment and academic freedom," Zakaria said. "But in this instance Yale Press was confronted with a clear threat of violence and loss of life."

Just sayin'...
