Radicals are not going to disappear. They're going to go underground. They're going to be hardened. And they're not going to be exposed to contrary ideas made by educated people who can make real, convincing, and persuasive arguments to deradicalise these people.

People sometimes say I broke an oath of secrecy - one of the early charges leveled against me. But it's a fundamental misunderstanding, because there is no oath of secrecy for people who work in the intelligence community. You are asked to sign a civil agreement, called a Standard Form 312, which basically says if you disclose classified information, they can sue you; they can do this, that and the other.
