Describing Germany's loss in WW2 as 'affecting their foreign policy a little' represents a profound disconnect with reality, which is that WW2 fundamentally reshaped the entire world, cemented the US as a superpower, set up the USSR for its rise, split Germany in two (with major political effects to this day), ended European empires (UK, French), and ultimately brought about the EU. And those are just some of WW2's effects, which would have all gone completely different directions if Germany or Japan had won.

This is an elite narrative. What happened to normal people? In the real world? Germans still speak German. Germany is still very wealthy, many of the same companies are still around; including those which supported the Nazi war effort like Hugo Boss and Mercedes Benz. German chemical industry is extremely successful... Population of Germany exceeds that of France...

How did Germany's defeat actually negatively affect things for the people in the long run?

One of my ancestors (French side) had to close their business because they made the decision to keep paying for employee wages during the war while their business was forcibly put on hold by the French government... Winning the war didn't mean much to them... Mercedes people who made the German war machines were filling their pockets throughout the entire war. Didn't even negatively affect their reputation!

What happened to normal people is very different.
