Editing Abu Nidal (section)

=== Personality ===
Abu Nidal was often in poor health, according to Seale, and tended to dress in zip-up jackets and old trousers, drinking whisky every night in his later years. He became, writes Seale, a "master of disguises and subterfuge, trusting no one, lonely and self-protective, [living] like a mole, hidden away from public view". Acquaintances said that he was capable of hard work and had a good financial brain. Salah Khalaf (Abu Iyad), the deputy chief of Fatah who was assassinated by the ANO in 1991, knew him well in the late 1960s when he took Abu Nidal under his wing. He told Seale:

Seale suggests that Abu Nidal's childhood explained his personality, described as chaotic by Abu Iyad and as psychopathic by Issam Sartawi, the late Palestinian heart surgeon.<sup>[33][14]</sup> His siblings' scorn, the loss of his father, and his mother's removal from the family home when he was seven, then the loss of his home and status in the conflict with Israel, created a mental world of plots and counterplots, reflected in his tyrannical leadership of the ANO. Members' wives (it was an all-male group) were not allowed to befriend each another, and Abu Nidal's wife was expected to live in isolation without friends.<sup>[34]</sup>
