At the time it was one or the other. It was okay until Adolph went bad on the jews and started WW2.
yes okay on that but Adolpho was pretty clearly heading in the war and genocidal directions long before he actually launched them. It was predictable, it was predicted— it was foreseeable, it was foreseen by many. (quite like the Iranian IslamoNazis today). Yet, USA industry kept building factories for Hitler, foreign capital kept pouring into Hitler’s Germany, and many politicians in UK and USA were advocating for appeasement, thereby enabling or speeding up his preparations to launch WW2.
I would say he made at least 2 big mistakes.
1. invading Russia (Russia has lots of patience and territory AND WINTERS to frustrate ground invasions)
2. murdering the Jews (from the Jewish scientists alone who managed to escape, the Allies were greatly strengthened through advanced electronics, missile technology, the atomic bomb, and more).
His two mistakes above were related in that his generals pleaded with him to release trains to carry troops and supplies to his troops on the eastern front. But he refused because he was using the RR’s to carry captured Jews en masse to his death factories, instead. This left German troops very under-supplied, even ammunition and food rations were made scarce. Had Hitler listened to his generals, his war could have worked out quite a bit better for him.
