I see that somebody or other has resurrected on old fake quotation attributed to Nikita Khrushchev, former premier of the Soviet Union:
We cannot expect the Americans to jump from capitalism to Communism, but we can assist their elected leaders in giving Americans small doses of socialism until they suddenly awake to find they have Communism.
This one is being dragged out by the usual scumbuckets as an anti-Obama line. I found it in a comment thread here, for example.
It is, of course, completely bogus. It is one of many "quotations" manufactured by the far right during the Cold War and first turned up in John Birch society circles in 1960. See They Never Said It, p. 59 (page image here).
