Great Report. It's a must read for anyone interested in Iran.
Iran is a state that must be assessed largely in terms of its capabilities, not its intentions. Its political structure is too unstable to predict, and its choice of defensive or offensive options is more likely to be determined by its perceptions of future opportunities and risks than its current policies and strategy. Seen from this perspective, Iran is not a “weakling,” but neither is it capable of major aggression or becoming a regional “hegemon” if it meets effective resistance from its neighbors and the US.
