The ideology of a regime significantly impacts its foreign policy by shaping its priorities, values, and interactions with other nations. For instance, a regime rooted in liberalism may prioritize diplomacy, human rights, and international cooperation, while a regime influenced by nationalism might focus on sovereignty and protectionist strategies. Ideological frameworks inform decisions regarding trade agreements, military alliances, and humanitarian efforts, affecting a country's global posture. Moreover, ideologies can dictate the degree of engagement with international organizations and treaties, influencing how a nation positions itself in the world.
