The [George W.] Bush administration marked a very serious and profoundly negative turning point - not just for the nation, but for the international order, because we started to govern on the idea of "might makes right." And that's a very old, toxic and infectious idea.

Extremists are not going to disappear.

When it comes to political engagement, I'm not a politician - I'm an engineer.

Richard Nixon got kicked out of Washington for tapping one hotel suite. Today we're tapping every American citizen in the country, and no one has been put on trial for it or even investigated. We don't even have an inquiry into it.

The reality is if we sit back and allow a few officials behind closed doors to launch offensive attacks without any oversight against foreign nations, against people we don't like, against political groups, radicals, and extremists whose ideas we may not agree with, and could be repulsive or even violent - if we let that happen without public buy-in, we won't have any seat at the table of government to decide whether or not it's appropriate for these officials to drag us into some kind of war activity that we don't want, but we weren't aware of at the time.

From the very beginning, I said there are two tracks of reform: there's the political and the technical. I don't believe the political will be successful, for exactly the reasons you underlined. The issue is too abstract for average people, who have too many things going on in their lives.

It is interesting that so many people who become disenchanted, who protest against their own organizations, are people who contributed something to them and then saw how it was misused.
