Some have similarly argued that Nazis provided the clearest Keynesian experiment in the 1930s. To a certain extent, this is obviously true. Just as we must admit that Nazi rocket technology was ahead of its time, so we must admit that they implemented certain Keynesian ideas when other Treasuries were still wringing their hands.
However, the character that dispairs at the end of the comic over Nazi rocket building acumen need not draw the same lesson from macroeconomic policy! By the forties we were doing Keynesianism too, without the nasty Nazi baggage. Indeed, as Brad Pitt's character noted in Inglourious Basterds - aggregate demand and killing those very Nazis was virtually identical: "our business is killing Nazis - and business is booming". Why anyone would consider saving Europe and East Asia from the wave of fascism washing over it a waste of resources (as some critics of the idea that WWII got us out of the depression suggest) is utterly beyond me. As far as I'm concerned, taking the cards we were dealt as given, it's some of the best money we ever spent. Hitler practiced economic policy that aided the German recovery. Roosevelt did it better, and defeated the Nazis to boot. Truman did it better, and made a huge human capital investment in prime age males and physical capital investment in Europe to boot. Eisenhower did it better, and gave us an interstate highway system to boot. Perhaps it was wise to pluck marginally attached Nazi party members for use at NASA. But don't send a Nazi to do an American Keynesian's job.
