I've spent a lot of time working on declassified documents - and they do get declassified after decades - you look at the record of declassified documents, and they are mostly concerned with keeping what the government does secret from its own population. It's mostly defense of the power system from its own population. Very little is authentic security.

There is a big difference between tweeting to your friend about something that is happening and having a real personal relationship with people.

There is a considerable polarization taking place here, increasing the gap between rich and poor. It's most dramatic in Third World countries, of course, but in the rich countries it's also very noticeable.

I don't claim to know a lot about Mexico, but I did talk to quite a number of left Mexican intelectuals, and they all said the same thing. That there's a lot of popular, kind of, concern and activism, but it is very fragmented. That the groups have very specific, narrow agendas and they don't interact and cooperate with one another. Ok, that's something you have to overcome to build a mass popular movement. And that's, media can help, but they also benefit from it.

If something comes along that you don't like, there are a few sort of four-letter words that you can use to push it out of the sphere of discussion. If you were in a bar downtown, they might have different words, but if you're an educated person what you use are complicated words like "conspiracy theory" or "Marxist." It's a way of pushing unpleasant questions off the agenda so that we can continue in our own happy ideology.

When something like this [2003 invasion of Iraq] takes place, the international law professionals have a complicated task. There is a fringe that just tells the truth: Look, it's a violation of international law. But most have to construct complex arguments to justify it as defense counsel. That's basically their job, defense counsel for state power.

Personally, I am uneasy about the notion of "a politically engaged university," for reasons I wrote about over 30 years ago, at the height of protest and resistance (reprinted in For Reasons of State).
