This isn’t a surprise at all.
Neither me. The French have a reputation among the uninformed as a poorly-motivated, surrendering people.
Any serious student of history, however, will know the French as one of the most warlike, toughest nations in Europe. The Second World War was an utter anomaly, they are the land of Napoleon, the most fearsome conqueror to hit the continent in centuries.
And the continent itself, is the inventor of the concentration camp, the genocide, and the concept of ‘total war’.
The Muslims would be wise to get out now, on favorable terms.
