[...]The United States doesn't need a lot of new grads to explain "why they hate us." What it needs are people who are so persuaded of its mission in the world that they are prepared to undergo some hardship and risk to advance it.

That demands cultural self-esteem and self-mastery—the true purpose of an elite education. It doesn't require a working knowledge of Arabic.
