Political ideologies manifest in international relations through the principles and values that guide countries in their interactions and policies. For example, liberal ideologies tend to emphasize human rights and democratic governance, driving nations to engage in multilateral partnerships and advocacy. Conversely, realist approaches focus on national interests and power dynamics, often leading to more isolationist or aggressive foreign policies. These ideologies shape alliances, conflicts, and negotiations, influencing how states respond to global challenges and collaborate on issues like trade, security, and climate change.
