The Third World Term Should Be Disbanded

The third world term should be disbanded and not to be used any more. It is one world and not three? Where is the first, the second, the third ..., any fourth? This is total carry on nonsense from time had past and era of cold war that does not exist. The distinction between what was called advanced industrialized countries and the rest of the countries has been blurred. Look to China with their plan to land on the moon. Look to India and its industrial growth. Look to too many other countries, South Korea and else. The third world term is nonsense and should be abandoned never mind and add to all that it has racist connotations.
