International organizations promote political stability by fostering diplomacy, facilitating cooperation among states, and addressing global issues. Through forums like the United Nations, they enable dialogue and negotiation, helping to resolve conflicts peacefully. These organizations also establish normative frameworks, setting guidelines for state behavior and encouraging adherence to international law. By providing a platform for small and large nations alike, they help mitigate disputes and promote collective action on issues such as security, development, and human rights, thereby contributing to lasting stability.
