Modern World Wars and Their Impact on International Relations

Modern World Wars, which include major conflicts such as World Wars I and II, have had a significant impact on international relations. The consequences of this event not only changed the political map, but also affected the global economy, culture and security system. First, World War I (1914-1918) resulted in the collapse of a number of major empires, including the Austro-Hungarian Empire and the Ottoman Empire. This created new countries in Europe and the Middle East, leading to ethnic tensions and nationalism that are still felt today. These shifts in power formed the League of Nations, which aimed to prevent conflict through diplomacy. However, its effectiveness has proven to be weak. World War II (1939-1945) had a deeper impact on the world order. This conflict prompted the formation of the United Nations (UN) in 1945, which aimed to maintain international peace and security. The UN encourages cooperation between countries and becomes a platform for diplomatic dialogue, especially with the adoption of the Universal Declaration of Human Rights which emphasizes the importance of human rights. From an economic perspective, the war brought structural changes to the global market. The Marshall Plan launched by the United States helped Europe recover after the war, strengthening relations between the US and Western Europe. This led to the formation of NATO as a military alliance, in response to the Soviet threat, changing global geopolitical dynamics. Global conflict also strengthens the attitude of ending colonialism. Countries in Asia and Africa began to gain independence, forming a new, pluralistic international order. However, decolonization was also often accompanied by bloody conflicts that changed international relations. In the Cold War era, the world was divided into the Western bloc led by the US and the Eastern bloc led by the Soviet Union. Proxy wars occur in various parts of the world, which adds complexity to international relations. This creates a more strategic foreign policy from large countries whose ambition is to maintain their influence. The effects of this confrontation are still felt today. For example, the emergence of international terrorism and regional conflicts in the Middle East, which are the impact of inappropriate post-war policies. International relations are now also influenced by global issues such as climate change, the digital economy and cyber security. In the modern era, globalization increasingly interconnects countries. With the existence of new international organizations and free trade agreements, it is hoped that continued conflict can be minimized through cooperation. Diplomacy also plays a crucial role in responding to this new challenge. Multilateral strategies adopted through forums such as the G20 and COP are vital in building more harmonious and productive relations between countries. Modern world wars teach that security and prosperity are interrelated and depend on international collaboration. Finally, the impact of the World Wars on international relations suggests that although conflicts can be devastating, they can also be a catalyst for closer cooperation between states. Lessons from the past must be integrated to create a safer and more stable world. Every country is now faced with the challenge of adapting and supporting each other in facing the ever-growing problems of globalization.
