Will Europe Go Gently into the Goodnight?

In Oct. of 732 Charles 'The Hammer' Martel defeated a Muslim army at Tours in modern day France halting the aggressive spread of Islam into Europe for seven centuries until Byzantium fell to the Turks in 1453. Soon after the fall of Byzantium Spain finally expelled the Muslims and set off four hundred plus years of European expansion, discovery, enlightenment, and domination of almost the entire globe. Once, Europe was strong, proud, confident, and unafraid to assert itself. Europe gave birth to the Renaissance and the Enlightenment, movements that generated tremendous advances in art, science, civil liberties, and the rights of the individual and eventually birthed the United States of America.
Today, Europe is weak, mired in a political correctness malaise that will ultimately prove to be its end.
In 2006 Muhammar Khadaffi said, "We have four million Muslims in Albania. There are signs that Allah will grant Islam victory in Europe – without swords, without guns, without conquests. The fifty million Muslims of Europe will turn it into a Muslim continent within a few decades. Europe is in a predicament, and so is America. They should agree to become Islamic in the course of time, or else declare war on the Muslims."
Given the rate of Muslim immigration into Europe, the high Muslim birth rates, and the head in the sand attitude of most Europeans it seems, in time, Khadaffi will be proved right because Europe won't take Khadaffi's advice and "declare war on the Muslims".
Europe, weak, ineffective, cowardly, unsure, won't be able to prevent its own end, even as it has become obvious, because it is paralyzed by cultural guilt and an inexplicable pacifism that will prevent them from ever raising a hand in defense of themselves, their homes, their countries and their culture. Europe has either forgotten its past or has willfully rejected it.
When the Notre Dame in Paris is converted to a Mosque, as was the beautiful Hagia Sofia in Byzantium, will the Europeans finally act? Or will it be too late and we will all wake up to find that Europe, the foundation of Western culture, has indeed gone gently into the goodnight.
