The significance of the World Wars in shaping modern geopolitics lies in their profound impact on international relations, national boundaries, and the balance of power. After World War I, the Treaty of Versailles paved the way for significant geopolitical reshuffling, laying the foundations for future conflicts. World War II led to the emergence of the United States and the Soviet Union as superpowers, resulting in the Cold War and the division of the world into spheres of influence. These events redefined national alliances and international policies, influencing global governance structures still relevant today.
