You never heard of the Wobblies?
From a phamplet of 1924 called "One Big Union":
"The workers of the world, conscious of their historic mission, will learn to avoid the mistakes they would make should they depend on other forces than their own industrial power for the solution of the world's problem. Agencies and institutions deriving their lease of life from the industrial masters of today cannot be looked to for support. They may feign being in favor of radical changes in the effects. They will, however, strenuously, even violently oppose any attempt at destroying the base, or the cause. They will strive to perpetuate the wages system at all costs.
The working class alone is interested in the removal of industrial inequality, and that can only be accomplished by a revolution of the industrial system. The workers, in their collectivity, must take over and operate all the essential industrial institutions, the means of production and distribution, for the well-being of all the human elements comprising the international wealth producers."

Socialism, it its purest form, is international in nature, and by definition precludes nationalism.
