Political ideologies significantly affect foreign policy formulation by framing how nations perceive their role in the world. For instance, a liberal ideology may promote multilateralism and diplomacy, emphasizing cooperation to solve global issues, while a realist perspective may prioritize national interest and security. These ideologies influence decisions regarding military intervention, trade agreements, and international alliances. The prevailing political ideology thus shapes a nation’s stance on global challenges, guiding its strategies and interactions with other countries on the world stage.
