Trotsky was doomed by his basic perspective, because once the bureaucracy became aware that it had evolved into a counterrevolutionary class on the domestic front, it was bound to opt for a similarly counterrevolutionary role in other countries (though still, of course, in the name of revolution). Trotsky’s subsequent efforts to create a Fourth International reflect the same inconsistency. Once he had become an unconditional partisan of the Bolshevik form of organization (which he did during the second Russian revolution), he refused for the rest of his life to recognize that the bureaucracy was a new ruling class.
