Iran

This chapter analyzes Iran’s foreign policy through the conceptual lens of niche diplomacy and emerging middle-power agency, arguing that Tehran’s external conduct reflects a dynamic interplay between structural marginalization and strategic adaptation. Against the backdrop of sanctions, geopolitical isolation, and domestic vulnerabilities, Iran has developed a selective, high-yield diplomatic repertoire that converts limited material capacity into asymmetric leverage. Theis chapter traces the evolution of Iran’s twenty-first-century foreign policy, showing how ideological commitments rooted in the 1979 Revolution intersect with pragmatic imperatives of regime security, economic survival, and regional influence. It examines Tehran’s reliance on proxy networks, energy diplomacy, strategic connectivity corridors, and religious-ideological instruments as core domains of functional specialization. These niches enable Iran to sustain influence across multiple regional theaters despite intensifying pressures, fragmentation within the Axis of Resistance, and deepening economic constraints. Ultimately, this chapter argues that Iran embodies a form of “pragmatic revolutionism,” a hybrid strategy that combines ideological posturing with adaptive statecraft, revealing both the utility and fragility of middle-power performance under sustained coercive conditions.
