Wahhabism, a messianic, jihad-extolling form of Sunni fundamentalism whose international expansion promotes, among other things, the subjugation of women and the death of “infidels.”
It is – to quote Obama’s description – a “perverted interpretation of Islam,” and the ideological mother of jihadist terrorism. Its offspring include Al Qaeda, the Taliban, Boko Haram, al-Shabaab, and the Islamic State, all of which blend hostility toward non-Sunnis and anti-modern romanticism into nihilistic rage.
