WI Geramn chancellor Adolf Hitler didn't have that sudden heart attack that killed him in January 1935?
Him not dying would probably nip European socialism in the bud and contain the rise of the USSR. A direct war with Russia is pretty much ASB (for one, Poland is in between them, and Poland had a military that could equal whatever Germany manages to muster (and would never consider alliance with so many germans in its lands) - and for another, any hostile move towards Poland brings in the Czechs and French (who had the biggest army in the continent) and maybe even the British. Nobody is stupid enough to do that, and nobody is skilled enough to outmaneuver all of them.)
perhaps he allied with the USSR to divide up Poland? sounds ASB, but if stalin somehow died and was replaced, maybe. I doubt the french would want to mess with russia![]()
