Since the end of the Cold War, the Non-Aligned Movement has been forced to redefine itself and reinvent its purpose in the current world system. A major question has been whether any of its foundational ideologies, principally national independence, territorial integrity, and the struggle against colonialism and imperialism, can be applied to contemporary issues. The movement has emphasised its principles of multilateralism, equality, and mutual non-aggression in attempting to become a stronger voice for the global South, and an instrument that can be used to promote the needs of member nations at the international level and strengthen their political leverage when negotiating with developed nations. In its efforts to advance Southern interests, the movement has stressed the importance of cooperation and unity amongst member states, but as in the past, cohesion remains a problem since the size of the organisation and the divergence of agendas and allegiances present the ongoing potential for fragmentation. While agreement on basic principles has been smooth, taking definitive action vis-à-vis particular international issues has been rare, with the movement preferring to assert its criticism or support rather than pass hard-line resolutions.
