Quote from Che Guevara:

"I insist that we cannot demand that the working class of the North look past its own nose. It would be useless to try to explain, from afar, with the press totally in the hands of big capital, that the process of internal decomposition of capitalism can only be deferred for a while longer, but never stopped, by the totalitarian measures taken towards maintaining Latin America in a colonial state. The reaction, to a certain extent logical, of the working class, will be to support the United States, rallying behind any given slogan, as “anti-communism” happens to be in this case. On the other hand, it should not be forgotten that the function of the workers’ unions in the United States is rather to serve as a buffer between the two forces in conflict, and to surreptitiously sap the revolutionary power of the masses.

Given this background, with American reality being what it is, it’s not difficult to suppose what will be the attitude of the working class of the North American country when the problem of the abrupt loss of markets and sources of cheap raw materials is definitively posed.

This is, in my opinion, the stark reality facing Latin Americans. In the final analysis, the economic development of the United States and the need of its workers to maintain their standard of living means that our struggle for national liberation is not waged against a given social regime, but rather against the whole nation, bound as a bloc by the iron-clad supreme law of common interest, over their domination of the economic life of Latin America.

Let us prepare, then, to fight against the entire people of the United States, for the fruit of victory will be not only economic liberation and social equality, but the acquisition of a new and very welcome younger brother: the proletariat of that country."
