Is it ISIS or iceuul? which a won is it?
Neither. It’s DAISH. (Pronounced da-eesh.)
(It’s FARC, not RAFC; ETA, not BHF; the PKK, not the KWP. I see no reason that Islamist terrorist groups shouldn’t be treated like Communist and nationalist terrorist groups and have an acronym in their own language, rather than an acronym made out of a translation of their name into English.)
