They are Muslims from Bosnia. That’s why they look white.
Eastern European Muslims, like Bosnians and Chechens, can be a strange lot. They're Muslim, no doubt about that, but many of them drink alcohol, eat pork, dress Western, etc.
During the Chechen war against Russia, many Arab "freedom fighters (i.e. terrorists) joined the conflict and almost immediately tried to get Chechens to conform to traditional Arab Muslim values which the Chechens wanted no part of. The Chechens grew to hate these Arabs fighting alongside them almost as much as they hated the Russians they were fighting against.
Looking at these girls, they look Slavic and were likely raised far more permissively than they would've been growing up Arab Muslims. I'm sure they were in for a shock when they arrived in Syria with their iPhones and wearing makeup and blue jeans.
Oh well...
Islam may have been stopped at the gates of Vienna in 1683, but the west has been in surrender to Islam for decades now.
Europe and America have made a tragic error. We ourselves elected a Muslim for our President, and we did so just 7 years after 911.
Europe is rapidly becoming Eur Arabia.
