International cooperation is vital in politics as it facilitates collaboration between nations to address global challenges such as climate change, security threats, and human rights. It fosters diplomatic relations and creates frameworks for collective action, enhancing stability and peace worldwide. Cooperation can occur through treaties, alliances, and international organizations like the United Nations. By working together, countries can pool resources, share knowledge, and develop common standards, leading to more effective policy outcomes. This interconnectedness often promotes mutual trust and diminishes the likelihood of conflicts.
