Most of what is said in "El Plan Espiritual de Aztlán" is not something we disagree with. It calls for nationalist liberation. Mostly what is missing is what concerns us.
The plan does not call for a socialist people's republic of Aztlán and in fact classes within Aztlán are equated. Related to this question is why the Chicano people may be the main force, but the revolution for Aztlán is a multinational struggle of oppressed nationalities. The reason for this is that we do not see a peaceful acceptance of a bourgeois Aztlán by the oppressor, but rather a turbulent revolution by the exploited and super-exploited of Aztlán that the oppressor will try to put down. Understanding this repression also means understanding why the struggle will be multinational, not just based in the Chicano nationality, but hopefully involving even Portuguese-speakers from South America.
The liberation of Aztlán is nothing less than crucial to all of Central and South America, and from there the whole Third World.
In the end, there will be two tendencies in the Aztlán national movement. One will be to seek peaceful acceptance of a bourgeois Aztlán republic, with a place for bourgeois Chicano culture in the world. In failing, it may end up paving the way for "diversity" in assimilation. The other road sees the cultural struggle, the education struggle etc. as subordinate to the liberation of territory on a socialist and anti-imperialist basis, very possibly a mortal blow to u.$. imperialism and a pivotal moment for the liberation of oppressed nations globally.
We of the Maoist Internationalist Movement do not see the imperialist country with $450 billion spent a year on the military giving in to an Aztlán peacefully. The peaceful creation of such a state would have to be conforming to the pressure of that $450 billion and it would be bound to entail a fraudulent kind of nationalism or really, just a rhetoric of "diversity" within the empire. That's why we see a revolution as necessary to the true liberation of Aztlán and such a revolution must find its social base in the exploited and super-exploited workers, namely the workers without legal working rights by Uncle $am's standards.
