he was answering while he was fishing in İstanbul, would he be in Russia if Lenin lived. He answered that We both would be fishing here if Lenin was alive.
I don't think so. Trotski was the body of Lenin who could only be a head for his poor health.
If Lenin had good health, he would not permit Trotski being his body. Trotsky would be a concurrent for Lenin, and Lenin would have killed Trotsky when no longer needed (or ok, Trotsky would be in Russia as he said, if he had killed Lenin).
Stalin was "Lenin and Trotski in the same body", he didn't need a concurrent Trotsky.
Like I already said in the forum, Trotsky wrote in 1904 in "Our political tasks", more than 30 years after Bakunin, that communism/bolshevism was leading to power-of-only-one/stalinism (but Trotski was aiming Lenin). (Many anarchists too forbid this warning).
But, as Lenin let Trotsky be his body, this power corrupted Trotski who finaly agreed their stalinism as he was half part of it. But he finally could not be the stalin (Stalin went), so he went crying afterward that it was not fair.
