The Muslim problem in Europe is tailor made for the likes of Al Qaeda and their Arab patrons. As this culture war intensifies it's possible that radical Islamist groups in the Middle East will attempt to arm, equip and train homegrown extremists clustered around Europe. It's probably happening now. The tinderbox could be ignited by a series armed attacks on civilians and the bombing of historical monuments and sites like the Louvre or the Tower of London. The battleground would be the cities with NATO troops facing weeks or months of destructive urban warfare.
If this is the fate of Europe better for it to happen now. Time is on the side of the enemy. Osama Bin Laden predicted that Al Qaeda and its followers would turn the West into a police state. Bin Laden’s allies are modern liberals and the corrupt mass media they dominate.
