The External Needs and Goals of States

In an increasingly interconnected world, no state can achieve its external needs and goals in isolation. The complexity of global challenges—climate change, pandemics, terrorism, migration, and technological regulation—demands cooperative solutions. Multilateralism, the coordination of national policies through international institutions and agreements, has therefore become an essential mechanism for pursuing external objectives.

Through institutions like the United Nations, World Health Organization, and regional organizations such as the African Union or the European Union, states can collectively manage shared problems while legitimizing their actions through international law. For smaller or less powerful states, multilateralism provides a platform to amplify their voices and safeguard their interests. For larger powers, it offers a framework for managing competition and stabilizing global order.

Nonetheless, tensions between national sovereignty and international cooperation persist. Rising nationalism, protectionism, and geopolitical rivalry have challenged the post-World War II liberal order. Yet, even in periods of retrenchment, the need for cooperation remains a structural reality of the international system. The evolution of global governance thus reflects the ongoing negotiation between states’ external needs for security and prosperity and their collective goals of stability and order.
