International relations is the study of how countries interact with one another. It involves understanding the political, economic, and social relationships between nations. Key topics include diplomacy, trade agreements, and international organizations like the United Nations. These interactions can lead to cooperation or conflict, depending on the interests of the countries involved. The field also examines global issues such as climate change, human rights, and security challenges. Scholars and policymakers analyze these relationships to promote peace, stability, and development worldwide. By studying international relations, we can better understand the complexities of global affairs and the impact of decisions made by governments.
