And that's where the responsibility of the ostensibly "moderate" Muslim world lies.
The West—Christianity—the rest of the civilized world—whatever you want to call it—shouldn't have to be the ones that solve this problem.
But it will be one of these two groups that imposes the remedy.
Therefore, it would be much better for the world, and for civilized Muslims, if the Muslim world destroyed this scourge for themselves. After all, it's their religion which has supposedly been hijacked!
It's a crisis of faith and culture for the entire Muslim world, and their very survival depends on it. They'd better wake up. Thus far, I see far too much timidity and denial in the so-called "moderate" Muslim community...
This is because the Jihadis who want to kill all the nonbelievers are the accurate followers of true Islam. It is the moderates who are the heretics, and they know it.
