Foreign policy is typically determined within a government through a combination of actions by the executive branch, advisory bodies, and legislative oversight. The President or prime minister often leads the formulation of foreign policy, guided by national interests, strategic alliances, and international obligations. Key players include the Department of State, military advisors, and foreign affairs committees in the legislature, which influence decisions through debates and approvals. Thus, foreign policy emerges from a multifaceted decision-making process that balances domestic priorities with the complexities of global relations.
