People have a right to privacy, but they also have a right to live. Fundamentally, we need cybersecurity and need to secure communications as well.

Al Qaida changes; Al Qaida adapts. We have to adapt as well. We rely on resources to do that. Reducing resources beyond a certain point will make us less able to adapt as our enemy adapts.

Global security can be formed or threatened by heads of state whose wisdom, folly and obsessions shape global events. But often it is the security practitioners, those rarely in the headlines but whose craft and energy quietly break new ground, who keep us safe or put us in peril.

Presidents get to decide how their intelligence is served up to them, and it's the job of intelligence to adjust.

The question is how much of your privacy and your convenience and your commerce do you want your nation's security apparatus to squeeze in order to keep you safe? And it is a choice that we have to make.

American political elites feel very empowered to criticize the American intelligence community for not doing enough when they feel in danger, and as soon as we've made them feel safe again, they feel equally empowered to complain that we're doing too much.
