I want to thank you for sharing the information you’ve presented. I agree with you that nationalism is a poison for the working class, and that much of the Latin American left sees only U.S. imperialism as the enemy while ignoring the real root of the problem: capitalism itself. This also leads to the tendency to idealize China and to justify nationalist governments such as those of Venezuela and Cuba.
For many years, I myself was shaped by nationalism, Stalinism, and Trotskyism. I followed figures like Pedro Albizu Campos, Rubén Berríos, and Juan Mari Brás, as well as groups such as the Puerto Rican Independence Party, the PSP, and later in the United States, the Socialist Workers Party and Workers Vanguard, among others.
Today, I find myself more aligned with the basic principles of the SPGB, especially its emphasis on global working-class unity, the rejection of nationalism, and the need to replace capitalism—not reform it—with a real socialist society based on common ownership and democratic control.
