What philosophy promotes the idea of multiple nations cooperating to address international issues?

The philosophy that promotes the idea of multiple nations cooperating to address international issues is known as multilateralism. This approach emphasizes collaboration among several countries to tackle global challenges, such as climate change, trade disputes, or security threats. It recognizes that many issues cross national borders and therefore need joint efforts for effective solutions.

In multilateralism, international institutions such as the United Nations play a crucial role in facilitating dialogue, negotiation, and cooperative action among states, fostering a sense of shared responsibility and collective problem-solving. This philosophy stands in contrast to unilateralism, which advocates for a single nation acting independently without relying on others. Additionally, it differs from isolationism, where a country opts to remain apart from the affairs of other nations, and nationalism, which emphasizes prioritizing national interests above international cooperation.
