The interaction of a state's domestic and international policy is a multidimensional subject that needs a thorough investigation. This scholarly paper aims to investigate the complex interaction between these two domains, offering light on their distinct goals, crossings, and tensions. This research aims to provide a deeper understanding of how states prioritize and harmonize their internal and foreign policy objectives in the pursuit of national interests by scrutinizing the available resources for pursuing these policies, identifying potential risks and challenges, and evaluating the impact of domestic political dynamics. Scholars and politicians can acquire useful insights into the complexity of statecraft and design more effective methods for achieving global security and prosperity as a result of this investigation.
