Hmm, perhaps either the German Danish war, (Yay, we got an Ally they got nobody!) which was how wars should be, quick, onesided (for my side), and with a minimum of civilian casulties.
Alternativly, perhaps the Indochina war (which had a lot of German participation due to the Foreign Legion enlisting whole Camps of German PoWs, interestingly, the Vietnamese treatment of those Germans was relativly bening, quite a couple ended up married with Vietnamese Women, nevertheless, they fought largely to the death at Dien Bien Phu).
After Algeria, most French forces there also claimed to have prefered Indochina.
