Read The Death of the West by Pat Buchanan. He uses UN #'s to project that there will be 2/3 fewer native Europeans in 2100. The majority of Europe will be Muslim.
Pope Paul VI's Humanae Vitae becomes more relevant everyday.
A big problem is their Muslim populations are disproportionately unemployed and on welfare. The ability of France to continue their welfare state is limited, and we will start seeing the cracks appear in the next few years. Expect civil unrest there within 5 years
Demographics is indeed destiny. The super-breeding muslim nations, ALL of which have overwhelming birthrates, will never get their economic houses in order. Thus the surplus will spill over into other nations that provide a greater opportunity. If as I suspect Islam is the source of the backwardness of all muslim nations due to myriad terminal flaws in the Religion of Peace(TM) and its concomitant mindset and worldview, and that Muslims will thus never peacefully integrate with non-Muslim neighbors, which oh by the way is a requirement of Islam, then nothing can result but strife, violence, and warfare.
Thus as Samuel Huntington put it, the "Bloody Borders of Islam." Christian, animist, Hindu, Buddhist -- it matters not. Islam is warring with all of them everywhere to some degree or another.
And just to come clean, I have read the Qu'ran. I remember it being inordinately concerned with the non-believers, the infidel. What is demands is obeyance. Period.
I hope to God I'm wrong, though.
That should not be much of a cocern. Sheer population cannot overwhelm a more economically and technologically superior society. If that was the case, China and India would have surpassed the United States long ago.
Look at the Islamic countries today. Over a billion people combined. Yet without Western assistance, these people would be leading a medieval existence. They would have trouble building a toothbrush factory on their own. In fact, they wouldn't even be able to pump the oil out of the ground below them if it wasn't for Western technology and know-how.
Left to their own devices, the entire Muslim world would resemble pre-war Afghanistan. Theirs is a brutal and repressive culture, virtually incapable of innovation and technologically capability. The men are raised to fight amongst each other and to kill at the slightest provocation. The women are raised to be submissive and docile, hidden away and incapable of contributing anything to their society other than produce babies who are doomed to lousy life, no matter what they sex is.
As the recent wars in Afghanistan and Iraq indicate, these are a primitive people who cannot hope to ever win a war against a technologically superior Western power such as the United States and Great Britain. Like a bumblebee can sting a bear, they can hurt us from time to time (such as on 9/11), but when the bear swats back, the bumblebee doesn't have a chance.
