The Dartmouth Conference is the longest continuous bilateral dialogue between citizens of the Soviet Union, now Russia, and the United States. It has been an attempt to create Sustained Dialogue on the changing nature of the relationship between the two countries for the purposes of preventing nuclear war. Furthermore, strengthening the relationship between these two powers has incredible implications for world peace and development. As of mid-2015, 142 3-day dialogues have been held under the auspices of the original Dartmouth Conference.
