The Polish Army was defeated, but not without a fight.
The French Army was defeated, but not without a fight.
The Yugoslavians were NOT defeated at all. The Germans never did get them to surrender.

On the other hand:
The Italians were formally allied with Germany.
The Czecks and Slovacks fought with the Germans. Of course, they had been betrayed by the French and British at Munich.
The Spanish and Portugese were neutral but assisted the Germans in every way short of combat.
Switzerland was neutral but supplied Germany with arms (for cash, of course) throughout the war.
"Liberal" Sweden was neutral but supplied Germany with arms throughout the war.

It was a complicated fracas. Italy switched sides toward the end. France switched sides TWICE.
