This document provides an analysis of President Obama's global engagement policy through the lens of collective needs, fears, and identity, using US-Iran relations as a case study. It summarizes the history of US-Iran relations since 1953, including failed US engagement attempts and the implementation of sanctions. It argues that engagement failed because it did not acknowledge or address Iran's unmet needs, fears, and loss of identity stemming from US actions like regime change. While Obama initially pursued more diplomatic engagement through letters, this approach shifted back to sanctions and pressure when Iran did not immediately respond. The document analyzes this shift through the framework of human needs theory, arguing engagement must meet needs to build trust and compromise.
