Algeria became independent as a result of that successful war. And the Germans had dozens of divisions not pacifying anything but creating more partisans.You compare totally different situations. I can object to you that armed resistance in France, Low countries, Denmark, Norway, was almost non existent for a long time. Hell, even resistance in the occupied areas in the Soviet Union was non existent in 1941 and only started later.
I can give you examples of regular armies who defeated guerrilla insurrections, on top of my head :
French army in Algeria (yes, look it up)
Russia in Chechnya
Spanish army in Spain
Britain in India, Africa
etc etc...
you talk about Iraq, but the US army had very different rules of engagements than during WW2. I can guarantee that a handful of german divisions from WW2 would have pacified the country VERY quickly.
