“What will it take for Europe to wake from its complacent slumber?”
Europe will die in its sleep.
The Muslim immigrants are averaging four children per couple as opposed to 1.2 or so for the native populations. Muslims in France and elsewhere know its just a matter of a decade or two before demographics decide the issue.

It would take another “crusade” to be rid of them. That will never happen.
This world is going to wake up one day and be under Sharia Law. And all the “diversity idiots” will be saying “But I was all for you. I was on your side. Why are you chopping my hea.....”
When on nation falls the bordering nations will submit. It’ll be like dominoes.
