Conflict between countries is a complex phenomenon and is rooted in various causes. One of the main causes is differences in political ideology. Countries that have different systems of government, such as democracy versus authoritarianism, often experience tensions. Apart from that, economic problems are also an important factor. Economic instability, social discontent, and struggles for resources underlie many international conflicts. Natural resources also play an important role in conflict. Countries with abundant resources are often targeted by other countries who want to control them. For example, areas rich in oil or minerals often become points of conflict. This injustice in the distribution of resources can lead to tensions between countries. For example, the South China Sea dispute between several Southeast Asian countries and China shows how resources can lead to rivalry. Historical aspects also need to be considered. Many international conflicts are marked by negative historical legacies, such as colonialism or previous wars. This collective pain often continues to fester and leads to long-lasting resentment. For example, the conflict between Israel and Palestine is rooted in a history of land conflicts and national identity. In addition, countries often get involved in conflicts because of alliances. International organizations and political blocs, such as NATO and the European Union, play a role in creating military pacts, which sometimes leads to tensions. When one country is attacked, alliance countries become involved, magnifying the impact of the conflict. This shows how international ties can fuel global tensions. The impact of conflict between countries is devastating. First, the humanitarian impact includes loss of life, refugees and the suffering of civilians. War often destroys infrastructure, education, and health services, damaging the future of future generations. With more than 70 million refugees worldwide today, this impact is being felt widely. The economic impact is also significant. Conflict causes huge economic losses, damages trade, and reduces investment. Countries that invest heavily in military budgets often neglect other important sectors, such as education and health. This worsens social conditions and creates a cycle of poverty and injustice. Apart from the domestic impact, the conflict also shook global stability. International tensions can lead to sanctions, embargoes, and diplomatic isolation. International relations become tense, and crucial sectors such as free trade can be hampered. In this context, diplomacy becomes an important tool to defuse tensions and prevent wider conflict. Knowing the causes and impacts of conflict between countries is very important. This can help in formulating strategies to create global peace, stability and justice. Through international dialogue and cooperation, it is hoped that tensions can be managed effectively. In this way, we can try to prevent conflicts from occurring in the future.
