After watching Sky News early this afternoon of the truck drivers being slaughtered on the grounds of not being the right sect of this terrible religion (not shown due to sensitivities) but seen by Sky's foreign editor Tim Marshall, to my opinion the only answer is nuclear weapons, lots of them in a lillypad formation.
Kill this now before it spreads otherwise this will happen for years and spread like a cancer, and the only way to kill cancer is cut it out, burn it with radiation or poison it, otherwise it kills you.
