Sadly, that appears to be true. They have invited war into their country. But don't discount the possibility that Swedes literally surrender to their Muslim hordes and whomever is guiding them.
I suspect this is happening already. Political Correctness is a genuine culture and people killer. Swedes seem to have drank that Kool-Aid already. It is almost completely secular-humanist (only about 2% attend church regularly), hasn't had to fight a war in over 200 years, is socially very Liberal, and is extremely "peace" minded.
Sweden is low hanging fruit for the Muslim hordes.
