When I was a kid, three presidents told us we had to fight in Vietnam, Cambodia and Laos, because if we didn’t fight them over there, we’d have to fight them on the beaches of California. We believed. It was a lie.

I was a teenager during the Cold War, and several presidents told us we needed to create massive stockpiles of nuclear weapons, garrison the world, invade Cuba, fight in odd little places and use the CIA to overthrow democratically elected governments and replace them with dictators, or the Russians would destroy us. We believed. It was a lie.
