I'm afraid the 'clash of civilizations' has already begun - and in the opening round, Europe accepted an Islamic Trojan Horse. There are dark days in Europe's immediate future. This will be interesting. Unfortunate - but interesting nonetheless.
Given that the conflict is defined from the start as a fight to the death, you have a better chance of surviving by fighting to win. The sooner Europe fights off the Islamic swarm, the better. But it will not be a pretty picture even if Europe has the stomach necessary to win, not just fight.
