Somewhat more than half, according to polling.
Which is unsurprising, as those nations had been fighting for independence (from the Russians, from the Prussians, from the Austrians…) for centuries. Stalin was just the latest of many foreign oppressors.
Regarding the events of 1918-1920 and the relatively brief presence of Stalin in the Cold War…my point there is that the timing demonstrates that Western opposition to the USSR was not primarily motivated by opposition to Stalinism.
Stalin provided a very useful enemy demon, but he was not the cause of the Cold War. The ruling class of the West were not afraid of the Stalinist betrayal of communism; they were afraid that communism might succeed.
