Non-Alignment: Non-alignment is an independent movement that enables each nation to follow its own policies without joining any super power blocs nor coming under their influence. A non-aligned nation judges an issue on its merit. It upholds the rights of all people for freedom and allows them to have a choice of action on international issues. An important aspect of non-alignment is its antipathy to military alliance and its opposition to any form of imperialism. The Non-Aligned Movement has become one of the biggest peace movements in the world. The members of NAM are increasing steadily. At present, there are 108 members. President Tito defined NAM in the first summit at Belgrade, “This group of non- aligned countries is not a bloc, but a group of like-minded nations.” Though sometimes it is referred to as the Third Bloc NAM is exactly what its name implies, a movement rather than an organisation.
