If Germany didn’t lost ww1 we wouldnt have had:
ww2.
The consequences of the end of the Ottoman Empire (a lot of middle east shits thats happening today, like Israel).
Maybe NO SOVIET UNION and NO COMMUNISM.
USA staying isolationist and not trying to gain influence here and there, nor participating in any war.
FRANCE out of the annoyance of Europe.
What would happened next? Dunno!
But at least in ww1 although even Italy fought against the Austro/Hungaric Empire and the Prussians (My grandad was 18 in 1917 and fought ww1 AND ww2), I still think the “bad guys” where absolutely France+Uk+Italy+USA+THE REST OF THE WORLD.
