He has been the initiator in France of the branch of the History of International Relations that deals with propaganda and pressure as a government weapon of foreign policy.[36] He also opened the way to the study of technocracy in international politics.[37] He has insisted that religion is an essential component of international politics and strove by conferences and other means to facilitate the collaboration between the four main religions of Judaism, Christianity, Islam and Hinduism.[38] He organised Orthodox dialogues with Iranian Shiites and Indian Hindus. He worked with Israeli Jews and fundamentalist Catholics from Quebec, where he, along with his students, produced the quarterly journal Aquila (eagle) which, with a double-headed eagle on the front cover promoted the Byzantine imperial idea in Catholic circles. He also worked closely with the Fethullah Gülen Sunni Muslim Movement (See Gülen's "Dialog of Civilizations Platform").
