After Siqueiros's attempt on his life, he wrote a letter to the Mexican attorney-general in which he accused all communist parties of being reserves of spies and murderers in the pay of the GPU. He also added the following detail:(112)
I do not exclude the possibility of the participation of Hitler's
Gestapo in the assassination attempt. Up to a certain point the
GPU and the Gestapo are connected with each other; it is possible
and probable that in special cases the same agents are at the
disposal of both . . . It is completely possible that these two
police forces co-operated in the attempt against me.
Conclusion: It is possible and probable that Siqueiros was a Hitlero-Stalinist agent; it is possible and probable that the Communists who agreed to work for Soviet agencies also put themselves at the disposal of the German agencies'
We said above that Trotsky had nearly identified 'Stalinist totalitarianism' and Nazism, but occasionally the nuance becomes imperceptible. In an article entitled 'The twin star: Hitler-Stalin' (6 December 1939), he claimed to prove that Stalin was Hitler's satellite! A little further on, he asserted that Stalin's aim in Spain had been to 'prove to London and Paris that he was capable of eliminating proletarian revolution from Spain and Europe with much greater efficiency than Franco and his backers' (Hitler and Mussolini).(113)
At a time when the Second World War had already broken out, to make the CPSU led by Stalin the principal enemy was to line up on the side of the counter-revolution. There was no third road. Merleau-Ponty, whose sympathy for Trotsky has never been denied, remarked that when he was killed the moment was approaching at which 'political life would have become impossible for him'.(114) It is to be regretted that the assassin's ice-pick prevented History itself from presenting Trotsky with the verdict on his last bankruptcy.
