Qurac had a metahuman terrorist/mercenary strikeforce dubbed Onslaught (formerly known as The Jihad), a frequent opponent of the Suicide Squad. The Joker served as Quraci ambassador to the US on two occasions, gaining diplomatic immunity (a retcon of a story in which he represented Iran and tried to assassinate the U.N., only being stopped when Superman - posing as a security guard - inhaled the Joker's lethal laughing gas and dumped it in space before it could do any damage).
