World Socialist Federation

The crisis of mankind is a "crisis of revolutionary leadership," and the Fourth International was established to resolve it.He advocates "continuous revolution" and "world revolution" and the establishment of a "world socialist federation."The Fourth International was preceded by the international left-wing opposition of Trotsky and others in 1929, claiming politically to inherit the platforms and resolutions of the first four congresses of the Communist International (Trotsky was the main writer of the declaration of the first three).So far, the Fourth International remains the largest and largest Trotskyist international organization.
