This monograph examines regional, multilateral track two dialogues in the Middle East and South Asia that are focused on arms control and other cooperative security measures. Unofficial policy discourse, or track two diplomacy, is an increasingly important part of the changing international security landscape, with the potential to raise new ideas and solutions to conflicts that, over time, may influence official policy. Talking to the Enemy considers how track two efforts in South Asia and the Middle East have socialized participants into thinking about security in more cooperative terms, and whether the ideas generated in track two forums have been acknowledged at the societal level or influenced official policy. Comparing the two regions, Kaye finds that South Asian dialogues, on Kashmir and other regional issues, have been more somewhat more effective than track two efforts in the Middle East, where lack of progress on official Arab-Israeli peace talks has also hindered unofficial regional dialogues. The author concludes with assessments of regional security trajectories in both regions, particularly proliferation dynamics, as well as suggestions on how to improve future track two efforts.
