General Franco used Moroccans to shatter the morale of the Spanish Left in the early days of the Spanish Civil War. And the Allies used French-commanded Moroccans to finally dislodge the Germans from strategic Monte Cassino in Italy. The French Allied general promised his Muslim troops that if they succeeded in driving the Germans off of the mountain, they would get 50 hours to rape Italian civilian women with impunity.
(Sophia Loren won her Oscar for a movie about this, but since then it appears to have disappeared down the memory hole outside of Italy.)
Personally, I think Europeans should try harder to get along with each other rather than import Muslims to spread terror and rape in Europe for partisan advantage in intra-European squabbles.
But then I’m some kind of wacko extremist, so I would say that, wouldn’t I?
