Capitalism's pre-eminence as a wealth generator means that every tyrant has to either embrace free markets or fall slowly into economic oblivion; but for markets to work, citizens need access to information technology and the freedom to use it - and that means having political power.

This link between economic and political liberty has been extolled by conservative thinkers for centuries, but the microelectronic age has strengthened it. Even China's deftly capitalist-yet-authoritarian government - which embraces technology while blocking Web sites and censoring chat groups - is doomed to fail in the long run. China is increasingly porous to news and ideas, and its high-tech political ferment goes beyond online debates.

Economic exclusion is especially perverse in cases where inclusion could work as a carrot. Suppose, for example, that a malignant authoritarian regime was developing nuclear weapons and you might stop it by offering membership in the W.T.O. It's a twofer - you draw tyrants into a web of commerce that will ultimately spell their doom, and they pay for the privilege by disarming. What president could resist that?

Correct! President Bush is sitting on the sidelines scowling as the European Union tries to strike that very bargain with Iran.
