I believe in Mine Kampf Hitler even predicted the cold war being divided into three “zones of influence” with the USA controlling North and South America, Japan controlling East Asia and Germany controlling Europe and Russia west of the Urals). We’ll never know but my contention the cold war would have been about the same just substitute Germany and the Reich for the USSR and the East Block. One side note The Reich would have made it to the moon first, those bastards.
Like history records, Hitler insisted on a hot war with the USA, no matter what he had said in his earlier writings (he also originally said that he merely wanted Jews out of Germany IIRC). And if he had held onto the nuclear scientists we got out of Germany, we could have seen an atomic holocaust too.
