Another one I was waiting to see whether a Classical reference would be found for (pardon that awkward sentence) ... the incipit from a piece in Newsday:

'It's Baghdad here." So say the rampaging Muslims of Paris, according to Newsweek. Those words are a reminder that the West and Islam are engaged in a worldwide struggle, along many different flashpoints - a clash of civilizations.

That's right: a clash of civilizations. From the Euro-jihad in Paris, to the anti-American violence in Iraq, to the intifada in the Palestinian territories, to the recent threat of the president of Iran to "wipe Israel from the map," to the string of terror-bombings in India and Indonesia, the common thread is a basic hostility between the Judeo-Christian West and the Islamic East.

That was the argument made by Samuel Huntington, a Harvard professor, in his 1996 book "The Clash of Civilizations and the Remaking of the World Order," in which he argued that different civilizations naturally find themselves in conflict. When the book appeared, many critics lambasted the author's cultural-historical pessimism. After all, didn't the experience of multicultural New York City in the '90s prove that everybody could get along, at least most of the time? Well, the last 10 years - most notably 9/11 in that same New York - have vindicated Huntington.

Indeed, this particular clash of civilizations has been going on for 14 centuries, since Islamic armies first swept over the Middle East, which at the time was mostly Christian. In fact, in 732 AD, a Muslim army nearly reached Paris before being defeated.

Other civilizational clashes go back to the beginning of recorded time. Herodotus, the ancient Greek chronicler known as "the father of history," wrote that Xerxes, king of the Persians, convened a warcouncil in which he told his nobles and generals about his plans to invade in 480 BC: "By this course, then we shall bring all mankind under our yoke, alike those who are guilty and those who are innocent of doing us wrong." In other words, the Greek historian painted an unflattering portrait of the Persian king. And some have criticized Herodotus as a mere propagandist for the Greeks.

But that's the point: Different cultures fight about everything, including their separate versions of historical truth.

... the whole thing.
