The situation is recoverable domestically if the Swedish government has the political will. A U.S. State Department estimation is that Muslims compose approximately 6% of the Swedish population (2014) and will compose around 10% by 2030, ceteris paribus. That is a very significant population but not necessarily an overwhelming one.
But the Swedish government and its globalist allies in the international media are in a serious state of denial. What it will take is a sea change in Swedish political administration and a significant increase in funding and personnel for law enforcement. And none of that is even remotely on the horizon.
Any demographic analysis like that really needs to be looking at military age males, say 18-35 or 40. I suspect the numbers are much worse there.
