I think you are way too optimistic.
Europe will lay down and submit. They are all but already there.
You are probably basing your assumption that there is still active energized Christians in Europe. There are churches still, but for the most part are filled with old people.

In a way, it takes a lot to awaken democracies... World war II showed it...
For instance, do you know that the most restrictive laws against Muslim immigration were now passed in... denmark? And that Norway has found a way to deny immigrant status to Muslim spouses of its own citizens?
By the way, while travelling in France this summer, I was flabbergasted to see how full the churches were (outside Paris) on sundays...
I note your comment, "Europe will lay down and submit. They are all but already there," and think that if I were a resident of Europe, I would hope to be an old person right now. The future there looks really bleak.
