Purpose: The accelerated developments since 2014 indicate a form of systemic entropy characterized by a state of increasing disorder. The unipolar order is experiencing unprecedented instability in its systemic equilibrium. Given Donald Trump's victory and certain international developments, it is anticipated that increasingly powerful shocks will impact the established order and system. Consequently, this research aims to provide a logical framework and strategy for Iran's foreign policy action within this context.

Question: This research seeks to answer the question: Which theoretical logic can provide the most optimal foundation for formulating the foreign policy actions of the Islamic Republic of Iran within the heterogeneous and chaotic state of entropy in the contemporary international system?

Method: This study employs a descriptive-analytical method and utilizes the theoretical framework of Neoclassical Realism.

Finding: Despite significant structural limitations and constraints on its agency within the international system, the Islamic Republic of Iran possesses considerable potential for a more active presence in the realm of systemic equations. This potential stems from its geostrategic, geo-economic, and geopolitical characteristics. Realizing this potential necessitates a theoretical framework for comprehending the operational realities and mobilizing resources effectively to achieve it.

Conclusion: Smart Realism – defined as the simultaneous combination of strengthening the domestic power structure and facilitating balancing actions with systemic-level powers – is proposed as the preferred strategy for Iran's foreign policy during the specified period.
