There is not great difference between him and Pablism, one of the best modern theoretician of Trotskyism was Celia Hart, The Pablists supported Castroism and the guerrillas concepts
Celia Hart was a member of the Central Committee of the Communist Party of Cuba, her stand is a little contradictory because the Trotskyists and the Anarchists were persecuted in Cuba at the beginning of the guerrillas revolt.
The Trotskyists also supported the government of Fulgencio Batista. for them he was an anti imperialist, but Trujillo was also taking an anti American stand and he was going to negotiate with the Soviets to avoid being overthrown
The Trotskyist that took a much better stand was Sedovia ( Natalia Trotsky ) who did recognize that the Soviet Union was a state capitalist country along with the personal secretary of Leon Trotsky known as Raya Dunayevskaya, and CLR James
