And how can this president outspend the USSR? Even in terms of raw economical power the USSR and Communist block outpowered the USA and capitalistic block, respectively, by the 70's, and some argue that by the end of 60's? The post-war Germany alone became the power-house of Europe AGAIN in what? 15 years? Not to mention the Italian Miracle. No, for capitalists to win the Cold War you would need POD inside the USSR, because without some counter-revolutionists taking power I doubt that Motherland could have lost.
What about Stalin surviving past 1928? I know, that he is often credited as one of the fathers of communism, but still, his projects of skipping the capitalism and jumping to communism directly are insane, as we now have not only theoretical, but practical proofs of Marks works. Also, as noted by Comrade Lenin, he had some authorithorian tendencies, that never showed OTL, of course, but give him some time and enough power, and who knows? Maybe it would even lead to a much more devastating GWII, or half of China under Chiang Kai-shek.
