Once you realise that ISIL basically wants to create WWIII and die in some sort of last stand against foreign powers, it becomes quite hard to figure out what to do with them.
The west, or the Russian coalition, or a Saudi-led group all have enough power on their own to defeat ISIL. The reason why it hasn't been done is no-one really know on what to do next, nevermind being able to agree with the other groups that want them defeated.
So really, this is a diplomatic issue with other foreign powers that we haven't been able to agree with for decades.
If that is thier attitude i would deport everyone but the Chinese, Who have not really annoyed anyone abroad in their Thousand year plus history.
5000 year + history

They're as old as any middle eastern civilisation.
That said the main reason they haven't really annoyed anyone "abroad" is because they have for the most part been too busy fighting themselves to keep control of their vast and diverse country. China hasn't been truly unified for most of their history. They also really hate the Japs, and popular opinion in the mainland would love a war against them.
Makes them about as warmongering and tolerant as the rest of the world in my book.
They are much more polite though, as their culture places a lot of emphasis on maintaining face and not being
openly rude or aggressive
towards others. But thats somewhat off-topic here
