What I have been suggesting is that it is best to regard the 'democratic peace' phenomenon as a subset of the broader general phenomenon of stable peace. In this connection, I would like to raise the question whether stable peace is possible only and has occurred only between countries that are democracies. A more comprehensive research program would look for historical cases of stable peace between countries that are not democracies, or between states only one of which is a democracy. Some of the research on 'zones of peace' by Professor Arie Kacowicz reported in his earlier publications and referred to in this volume moves in this direction. It is important to apply the distinction between conditional and stable peace also in such studies.
