It was in 2004, when American businessman Nicholas Berg's brutal execution by beheading was widely shown all over the Internet, that most Americans caught their first glimpse of the black flag of Islam. Hung on the wall behind Berg and his murderous executioners was a black banner with Arabic writing in white.

Since the murder of Nicholas Berg, in numerous al-Qaida videos posted online, the same black flag has been observed hanging prominently behind the speaker.

And now the same black flag is proudly flying high over the U.S. Embassy in Tunisia and is waving across the world.

Welcome to Obama's so-called "Arab Spring."
