Turns out the authors of the Curious George series barely escaped the Holocaust. Some day someone will likely trace significant parts of the US's post-war dominance to enormous numbers of extremely talented people who fled the ultimate expression of progressive doctrines. I think it's a real, and largely unchronicled, tragedy that the progressives in charge of US foreign policy at the time made it cheaper for the USSR and the Nazis to kill their undesirables instead of send them our way.
