> Letting them continue to alienate themselves amongst all the other Muslims on the planet by the way they treat their fellows (if you're Muslim, but don't believe in IS's specific notions of the caliphate, you're an apostate, and must be killed) will, in the long run, do more to destroy them than even nuking all of Syria ever could.
Waiting it out is not an option.

"Amid all the atrocities carried out by Isis — its massacres of civilians, its beheading of hostages, its pillaging of antiquities — the systematic violence the jihadists have carried out against countless enslaved women and girls never fails to shock. For months now, we've heard appalling testimony from women who escaped Isis's clutches, many of whom endured rape and other hideous acts of violence."
"Here's a chilling excerpt: "After attacking a village, [the Islamic State] splits women from men and executes boys and men aged 14 and over. The women and mothers are separated; girls are stripped naked, tested for virginity and examined for breast size and prettiness. The youngest, and those considered the prettiest virgins fetch higher prices and are sent to Raqqa, the IS stronghold."
"We heard about one girl who was traded 22 times, and another, who had escaped, told us that the sheikh who had captured her wrote his name on the back of her hand to show that she was his 'property'."
"Estimates vary, but there are believed to be somewhere between 3,000 and 5,000 women enslaved by the Islamic State. Many are Yazidis, a persecuted minority sect that the extremist Islamic State considers to be apostate "devil-worshippers," in part because of the Yazidis' ancient connection to the region's pre-Islamic past. The jihadists' treatment of Yazidi women, in particular, has been marked out by its contempt and savagery."
Here's Bangura again: "They commit rape, sexual slavery, forced prostitution and other acts of extreme brutality. We heard one case of a 20-year-old girl who was burned alive because she refused to perform an extreme sex act. We learned of many other sadistic sexual acts. We struggled to understand the mentality of people who commit such crimes."
