For Western Europe, it's too late...just on demographics alone, it will become Islamic.
Just get the nukes out of England and France before it happens.
Nope, much of Europe will rise up in time, Germany, Poland, even Austria will make it. Italy and UK will make it, France is probably toast, we'll have to remove their nukes. Their nuke plants are a bigger problem, damn things are everywhere. Maybe just bomb em, open the cores to the atmosphere, make the areas uninhabitable, it will depend how much time we get and if ANOTHER european shooting war starts.
Will Europeans have the stomach to defend their homeland? I doubt it. But they could if they wanted to. It would take Churchillian statesmanship.
One thing everyone seems to forget at their own peril is this simple fact.
Westerners excel at killing their enemies, once they finally decide to go to War.
They may be little slow at making that decision but once it is made it is bad news for the other guys.
