"The gist of Kagan’s intellectually stimulating and imaginative argument goes something like this: Americans are endowed with a disproportionate percentage of angelic, altruistic DNA compared with non-chosen others. Uniquely among nations, the United States wishes to make other people happier, freer, and wealthier by fighting against corruption and tyranny abroad."

Well, that is definitely "imaginative", yo. Like, you'd have to be higher than a kite to believe it.
