In 1969, Assad purged several Jadid loyalists, and from that point on Jadid had lost his preeminence in the state. In 1970, when conflict erupted between the Palestine Liberation Organization (PLO) and the Jordanian army, Jadid sent Syrian-controlled Palestinian troops of the nominally PLO-run Palestine Liberation Army, based in Syria, into Jordan in order to help the PLO. This action was not supported by Assad's right-wing Ba'ath faction, and the troops withdrew. The action helped trigger the simmering conflict between Jadid's and Assad's wings of the Ba'ath Party and army. The Syrian Communist Party aligned itself with Salah Jadid. The Soviet ambassador, Nuritdin Mukhitdinov was drawn in the power struggle. Hafez al-Assad was angered by Soviet influence in Syrian politics, so he decided to scare the Soviets by sending Mustafa Tlass to Beijing to procure arms and wave Chairman Mao's Little Red Book. In November 1970, Jadid tried to fire Assad and his supporter Mustafa Tlass, to which Assad responded by launching an intra-party coup against Jadid, dubbed the Corrective Movement. Jadid was arrested on 13 November 1970, and remained in the Mezzeh prison in Damascus until his death, while al-Assad would remain in power until his death in 2000. Jadid died of a heart attack in a hospital on 19 August 1993.
