I think a tad more “interesting” is the question of what would have happened had Germany won World War I? I think most historians (and I am but a casual student) would agree that the ramifications of WWI were quite a bit more profound than WW2.
Arguably, there very well might not have been a WW2 without the result of WW1 as it turned out. No doubt some lower level conflicts may have arisen intra-Europe because of the convoluted alliances that had been built up in the 19th century.
Almost certainly, there would not have been the rise of Naziism. There wouldn’t have been this disgruntled corporal named Adolf Hitler who, for better or worse, right or wrong, thought his nation had been sold out and betrayed by literally everybody.
And the Brits would not have obtained the power to divvy up the Ottoman empire into the present day states of Iraq and Israel and Jordan.
But Germany, in many respects a brand new country in 1870, patently stronger and more technically advanced than say Belgium and Holland and understandably lacking the overseas possessions aka colonies those smaller nations had come into over many many decades....always felt like the brunt of the neighborhood. A resentful position, again, right or wrong.
Well, had they won WWI it would be by a squeak. They lost the moment the USA entered the war (no patriotic speaking, just cold, hard facts) -- at the most they cold have hoped for a draw in 1918
If they won, then they would have still have the USSR (a monster they helped create) and the German workers would have risen to form their own Soviet states
Austro-Hungary too would have formed soviets. ditto Italy, France etc. -- remember that during the Polish-Soviet war the workers in the UK, Germany and France prevented supplies heading to Poland.
Net result if the Germans won WWI AFTER the Russian collapse is a Soviet union that would have been based in Berlin but stretching from the Atlantic to the Pacific -- over all of europe, russia, china
THAT would have been horrendous
After this Eurasian Soviet, it would have hit south, into the Ottoman empire and and the middle east and india.
