Take a look at this photo from Reuters, taken outside the Israeli consulate in New York on Tuesday.

The swastika inside the Star of David is predictably moronic and offensive. But cuter still is the placard on the right, captioned “Islam will dominate”, below a White House flying the black flag of Jihad and the Caliphate.

Here’s what the flag represents:

The Black Flag (al-raya) traces its roots to the very beginning of Islam. It was the battle (jihad) flag of the Prophet Muhammad, carried into battle by many of his companions, including his nephew ‘Ali ibn Abi Talib. The flag regained prominence in the 8th century with its use by the leader of the Abbasid revolution, Abu Muslim, who led a revolt against the Umayyad clan and its’ Caliphate. The Umayyads, the ruling establishment of the Islamic world at the time, were seen as greedy, gluttonous, and religiously wayward leaders. The Abbasid revolution, then, was aimed at installing a new, more properly Islamic ruling house that would keep orthodox Islam at the center of its regime. Since then, the image of the black flag has been used as a symbol of religious revolt and battle (i.e. jihad). In Shiite belief, the black flag also evokes expectations about the afterlife. In the contemporary Islamist movement, the black flag is used to symbolize both offensive jihad and the proponents of reestablishing the Islamic Caliphate.
