The last of Germany’s fighting men died around 1945. There is no one left to fight.
That applies throughout much of Western Europe. If the real German men were all killed at Stalingrad, so too were the French at Verdun. Von Falkenhayn's meat-mincing machine did exactly what was intended; it bled the French white and France has never recovered. It was just about the same with the British with the Somme and Ypres, although it took the second war to finish them off.
Western Europe simply will not fight to defend itself. Nor does it even admit that it is under attack. In fact they aren't even capable of the most basic of preservation instincts: breeding. And so Western Europe, as we once knew it, is really already dead.
Maybe the Poles will be nice and let the Volksdeutsche back into Silesia and Pomerania.
That's a silly statement. One could then say the same about the USA after the civil war, or France and Italy and Germany after WWI -- yet after WWI, the Germans were ready to fight again 20 years later, as were the Russians
Germany still has a strong army, but the mood is strongly against war. If that mood changed, they would change -- societies and cultures can change from war-like to peaceful to war-like in a generation or two.
