Internationalism is a political movement which advocates a greater economic and political cooperation among nations for the theoretical benefit of all. Partisans of this movement, such as supporters of the World Federalist Movement, claim that nations should cooperate because their long-term mutual interests are of greater value than their individual short term needs. Internationalism is by nature opposed to ultranationalism, jingoism, realism and national chauvinism. Internationalism presupposes the recognition of other nations as equal, in spite of all their differences. The term internationalism is often wrongly used as a synonym for cosmopolitanism. Cosmopolitanist is also sometimes used as a term of abuse for internationalists. Internationalism is not necessarily anti-nationalism, as in the Soviet Union and the People's Republic of China
