A Muslim religious nut. Basically, an Arab who is frustrated by the shitty living standards of his own country, and gets brainwashed by the equally shitty government into thinking it is the West's fault. Some actively resist the "invaders", and subsequently get shot, incinerated or blown up. All in the hopes of banging virgins in Heaven.
Al Qaeda did 9/11, killing 3,000 Americans. America & Co. then retaliated, resulting in more than 100,000 Arab deaths in Iraq alone. And still Islamists claim they are winning this war.
