Andrew Sullivan says it better than I:

Romano Prodi, the chief of the European Commission, puts it as bluntly as anyone: "It is clear that using force is not the answer to resolving the conflict with terrorists," Prodi said. "Terrorism is infinitely more powerful than a year ago." This is classic appeasement. And it's also demonstrably untrue. Al Qaeda has been seriously weakened since 9/11, thanks almost entirely to those countries, especially the U.S., that chose to confront it. But it seems clear to me that the trend in Europe is now either appeasement of terror or active alliance with it. It is hard to view the results in Spain as anything but a choice between Bush and al Qaeda. Al Qaeda won.

Heaven help us if Kerry wins.
