Functionalism, as another Idealist proposal for world order, argues for the organization of international cooperation not along the line of territoriality but of specific social and economic activities. It stresses cooperative nature of world politics rather than international conflicts and, as such, addresses the problem of war and peace indirectly. The assumption here is that cooperation in economic and social activities would gradually help states to achieve mutual understanding and solve their differences, that is, cooperation in nonpolitical issues would “spill over” to political issues.
