if Muslims start declaring caliphates and trying to form their own mini-countries within their ethnic enclaves that's exactly what the response will be.

See I don't think so. Just look at how Europe has responded to Muslims so far. They rape local women, set fire to churches, lob grenades at each other, and drive trucks of peace around, and nothing happens in response. Here in the U.S., after the city of Hamtrack, Michigan was taken over by muslims, the local white liberals just moaned and gnashed their teeth when the muslims banned LGBT nonsense on city property but nothing else happened in response.
