Or put another way- when will Europe wake up to the fact that Islamic men don't flock there because they seek enlightenment; they are there because they see Europe as the neighborhood slut and are treating her as such.
Good question.
When Islam cuts off their oil? When burning synagogues, follows the course of normal Islamic evolution, and people start exploding in the streets, or attacking the priceless artifacts and symbols of democracy and culture?
I half expected a plane attack on the eiffel tower, on the same day or week when the islamic radicals murdered our fellow americans in New York. I fear for Europe in that our family members... they are. Cousins, aunts, uncles, blood relatives, and often kindred in so many ways, Europe carried the torch of Western Civilization.
Now, they are unable to carry their own chambre pots, and complain to us, of their own stench. They are indeed easy victims. With (semi) fortress america at attention, I expect our interests abroad, will become targets of opportunity in Europe. As Islam cuts off their oil, and Europe bleats, I doubt Islam will let it off the hook. THEY may be foolishly counting on the bleating of Europe, with the scimitar held to her throat, to bring us to our knees.
Europe, may not be as aquiescent as Islam hopes. And WE will not be brought to our knees... Were I a musli, I would be VERY concerned about Allah's ability to protect, mecca, medina, the temple mount, and the capital cities of every arabic/islamic state from the wrath of the USA, Israel, Britain... and even France.
Like the genie of old... I think its time for Islam to get back in its bottle for a few thousand years.
