The September 11 attacks were major atrocities. . . . This was a horrendous crime . . . The primary victims . . . were working people: janitors, secretaries, firemen, etc. It is likely to prove to be a crushing blow to Palestinians . . . It is also likely to lead to harsh security controls, with many possible ramifications for undermining civil liberties and internal freedom.

One contribution scientists can and should make is to be clear and explicit about the limits of scientific understanding, a matter that is particularly important in societies where people are trained to defer to alleged experts.

The U.S. - the idea that the U.S. has introduced and imposed principles of international law, that's hardly even a joke. The United States has even gone so far as to veto Security Council resolutions calling on all states to observe international law. That was in the 1980s under Reagan.

The European reaction to Obama is a European delusion.

The idea that Hezbollah is acting as an agent of Iran is very dubious. It's not accepted by specialists on Iran or specialists on Hezbollah. But it's the party line. Or sometimes you can put in Syria, i.e. "Syrian-supported Hezbollah," but since Syria is of less interest now you have to emphasize Iranian support.

Take the US. Women were not even able to vote until 90 ago, at about the same time they gained the right in Afghanistan. Rights of former slaves were very limited until the 1960s, and in some ways still are. In these and other domains there has been progress in democracy, though still seriously flawed. In other dimensions - the control of concentrated wealth over the political process, for example, things have gotten much worse in recent years. And there is much more, in both directions.

There are by now declassified documents from the 1950s that tells you a lot about what's going on in Egypt and we should have known it then. It's about exactly what's happening, how we can disregard public opinion as long as the dictators we support are capable of suppressing their populations. So to hell with public opinion. That's all right there in the 1950's. That's not security. That's not security of the government. That's, if anything, security from its own population. And there's a lot of that.
