It’s salutary to remember that the C.I.A. poured hundreds of millions into culture. For example, there was a festival of atonal music in Paris in 1950, entirely funded by the C.I.A. Can you imagine a less attractive festival? They paid for tours by the Boston Symphony Orchestra and Abstract Expressionist art exhibitions. The aim was to persuade especially left-of-center European intellectuals that the United States was a powerhouse of culture, because there was a widespread assumption, so the C.I.A. believed, that Europeans thought America was just an empty-headed place of money and loudness, with no depth.
