An embassy is a foreign nation’s sovereign territory. Muslims who attack it and raise their black flag of Islam over it are “conquering” that territory for Islam. The Muslims who attacked the consulate in Benghazi and the embassy in Cairo saw themselves as liberating a chunk of infidel held territory for Islam, for the same reason that they attack Christian villages.
