Europe is weak and dying, it has neither the motivation nor the strength to prevail against Islam in her midst. Perhaps, should some symbolic place be laid to waste, the Eiffel Tower, St. Peter's Basilica, etc., they could be roused to survival but the madmen Moslems aren't that stupid. They will avoid hitting any target with the capacity to unite the world against them.
They are smart, and they haven't achieved enough success yet to become arrogant and allow that to cloud their judgement and/or actions. They are the most dangerous enemy any Nation/State has ever faced.
