Indeed, any effort to enrich human virtue is at risk, not only from evil sources, but also from conflicting political interests that are seeking ends that are good in themselves. Even working toward peace is not free of political risk. Scandal is sometimes the price of virtuous action. Perhaps that principle was learned first when imported food was donated to famine-stricken countries, only to discourage farmers from planting their fields. Peace as a mission is as complex as a military conquest.
Politicians forget sometimes that peacemaking is a private as well as public function.
The wisest course in the service of peace is to use advocacy resources for public education, and to monitor the political process as it works out public programs.
