During the 1960s, Iran transitioned from a client state into an emerging partner of America. Crucial to the analysis of this transformation is understanding how Iran progressed from a low-priority military aid recipient in the 1950s to a military credit purchase partner in 1964. The transformation was characterized by frequent difficulties and disagreements as the Shah’s demands and Washington’s ability and/or desire to fulfill those demands rarely coalesced until the twilight of the Johnson Administration.
