England seems to be the rock which breaks the revolutionary waves, the country where the new society is stifled before it is born. England dominates the world market. Any upheaval in economic relations in any country of the European continent, in the whole European continent without England, is a storm in a teacup. Industrial and commercial relations within each nation are governed by its intercourse with other nations, and depend on its relations with the world market. But the world market is dominated by England and England is dominated by the bourgeoisie.

Thus, the liberation of Europe, whether brought about by the struggle of the oppressed nationalities for their independence or by overthrowing feudal absolutism, depends on the successful uprising of the French working class. Every social upheaval in France, however, is bound to be thwarted by the English bourgeoisie, by Great Britain’s industrial and commercial domination of the world. Every partial social reform in France or on the European continent as a whole, if designed to be lasting, is merely a pious wish. Only a world war can break old England, as only this can provide the Chartists, the party of the organized English workers, with the conditions for a successful rising against their powerful oppressors. Only when the Chartists head the English government will the social revolution pass from the sphere of utopia to that of reality.

For england read "the imperial hegemon", for france read "the link in the imperialist chain that breaks"

Revolutionary dictatorship gotta press the reactionary hegemon hard and fight a world war against them. Otherwise there will be no global revolution and no communism, just endless counterrevolutions forever
