This was the mistaken line of Trotsky from the very beginning: to sacrifice the USSR for an abstract conception of world communism. This is exactly why Stalin had the anti-cosmopolitan campaign (and not because the anti-semitism allegations). The rootless in "rootless cosmopolitanism" denotes exactly this: that you want to further communism by abandoning the socialism you already have. Russian Jews who wished to leave the USSR to build Utopian kibbutzes in Israel did just this.
Meanwhile, the path that Trotsky sets for his newest wrecking project: "the Fourth International supports a struggle to the death against Stalinism" (Trotsky , pp. 75-76). And this, after he was expelled instead of killed as he should have been, after the Soviet consulate authorities even paid him $1,500 for ‘royalties’ as an author in Turkey (Broué , p. 632). It was a pure gesture of "do what ever the fuck you want, just stop wrecking, k?" but the fucker just couldn't stop. He was actually hoping that Hitler would topple the soviet leadership FOR him as he couldn't stop thinking of himself as the RIGHTFUL HEIR: "However, before going to hell, Hitler could inflict such a defeat on the Soviet Union that it could cost the head of the oligarchy in the Kremlin." (Trotsky , pp. 1258-59.) So while literally anyone with two functioning braincells understood that the future of world communism is inseparable from Russia and that the Great Patriotic War would decide whether the communist movement exists could survive or not, Trotsky was advocating a different understanding of "patriotism": "Soviet patriotism can’t be separated from the irreconcilable struggle against the Stalinist clique."
Such a great "New International" you got there.
