If you go back a century in Europe, all over the place people were speaking different languages. There were dozens of languages in France and Italy, and they're all called French [and Italian], but they were not mutually comprehensible. They were different languages. And they have mostly disappeared in the last century or so. Some are being preserved, like Welsh, some are being revived, like Basque or Catelan to some extent. There are plenty of people in Europe who can't talk to their grandmother because they talk a different language.

Whoever sets the agenda controls the outcome of the debate

If something is right (or wrong) for us, it’s right (or wrong) for others. It follows that if it’s wrong for Cuba, Nicaragua, Haiti, and a long list of others to bomb Washington and New York, then it’s wrong for Rumsfeld to bomb Afghanistan (on much flimsier pretexts), and he should be brought before war crimes trials.

Since James Madison day (and long before), there have been constant struggles over "democratic governance".

There is still much debate about whether torture has been effective in eliciting information - the assumption being, apparently, that if it is effective, then it may be justified.

If the most important revolutionary part of the George W. Bush Doctrine is that states that harbor terrorists are terrorist states, what do we conclude from that? We conclude exactly what Kissinger was kind enough to say: These doctrines are unilateral. They are not intended as doctrines of international law or doctrines of international affairs. They are doctrines that grant the U.S. the right to use force and violence and to harbor terrorists, but not anyone else.

If you sell me a car, we have perhaps made a good bargain for ourselves. But there are effects of this transaction on others, which we do not take into account. There is more pollution, the price of gas goes up, there is more congestion.
