NATO'S Poorly planned adventure in Kosovo has brought a critical question to the fore: just how should Americans define their national interest in the information age?

Global telecommunications have made humanitarian crises in far-flung places impossible to ignore. But before the United States embarks on another costly human rights crusade, Americans should recognize that moral values are only part of a foreign policy. Other essential priorities remain. If Washington neglects to handle the "A list," the consequences for global peace and prosperity will be dire.
