France?
Isn't that a third world country that is run by Muslims who burn car?
Shame.
The French engaged an annual ritual of surrender toward the Islamic pirates for many decades until the 1830s. Thomas Jefferson attempted to extinguish the Barbary pirates throughout his "millions for defense; not one penny for tribute" presidency, and James Madison carried the United States to its first victory over the Islamic armies in the Tripolitan War (1801-1815). The French naturally sided against the United States, continuously financing our enemies and outfitting their navy. We also defeated the French in several naval battles during the 1790s; indeed, the French threat to American shipping led Congress to commission a navy to defeat them.
But in the current conflict, the French formally surrendered in 1962, allowing millions of Islamofascist Algerians and other similarly inclined immigrants to join the tens of thousands of Islamists already terrorizing the country through the 1950s. Had the French defeated their enemies, Islamofascism today might exist only as a minor undercurrent in a few Arab societies. But the surrender of France only emboldened the Islamofascists, who set about attacking Israel, the Munich Olympics, the Achille Lauro, and numerous airliners. They also took control of Sudan, Iran, Iraq, Syria, and Libya. This movement flourished into the major world threat that now pesters us today.
Aside from a very brief period in the wake of the 11 September 2001 terrorist attacks when George W. Bush indubitably frightened them into submission, the French never have released their insistence on surrendering to the terrorists. They encumbered an American air force mission aimed at punishing the terrorist Great Socialist People's Libyan Arab Republic, whined and moaned incessantly on behalf of terrorists in the United Nations, subsidized an ongoing domestic Islamofascist demographic explosion, and actively assisted the genocidal terrorist butcher of Baghdad. So yes, the French have lived in surrender for forty-four years--they surrendered even before the United States entered this war.
Hell, Chirac caved to the rioters. So having run out of everybody else, the French have surrendered to the French.
