Derbyshire takes the larger view

and has a strategy to enforce it:

"So far as the jihadists elsewhere are concerned, I am happy to let them have Afghanistan, Sudan, Somalia, or any other donkey-powered dustbowl they want. They will only make these wretched places worse. I do think we should watch such jihadist states carefully, and act against them unapologetically and with major force if they look like making a nuisance of themselves."

Buckley asks some tough questions

"Two challenges are posed. The first is relatively manageable: Lower the flag on American universalism—not to half mast, but not as toplofty as it has been flying since the end of the Second World War. The second is tougher. Why is Islam burning bright? What on earth do they have that we don't get from Christ our King? If what they want is a religious war, are we disposed to fight it?"
