Following the Islamic revolution, Iran has consistently faced threats from neighboring countries and major global powers. In response to Iran's revolutionary stance and its challenging position in the international arena, the United States has imposed significant arms and military sanctions aimed at curbing Iran's influence in the region. However, drawing from historical lessons, Iran has adopted a deterrence strategy to counter external pressures. To compensate for its relative conventional military weaknesses and maintain deterrence against adversaries, Iran has prioritized the development and production of missile capabilities. This study delves into the development of Iran's missile capabilities and their correlation with U.S. arms embargoes. It seeks to answer whether these sanctions have effectively contained Iran's regional influence. Employing a Trend Impact analysis methodology that utilizes library resources, we will explore the trajectory of Iran's missile industry development under sanctions. Furthermore, we assess the efficacy of these sanctions on Iran's defense capabilities and military structure. The research findings indicate that U.S. military sanctions have failed to achieve their intended objectives and safeguard the interests of the U.S. and its regional allies. Contrary to assertions, the sanctions have strengthened Iran's missile capabilities and regional influence, solidifying the country's position as a regional power in the international system.
