Jordan Black September Conflict and Palestinian Expulsion (1970-1971)

SUMMARY

The 'Black September' conflict refers to a civil war in Jordan primarily fought between the Jordanian Armed Forces, led by King Hussein, and the Palestine Liberation Organization (PLO), led by Yasser Arafat, from September 1970 to July 1971 [9, 10, 13]. The conflict stemmed from the PLO's growing presence and influence in Jordan, which included attempts to challenge the monarchy, hijacking airplanes, and launching attacks against Israel from Jordanian territory [4, 10, 13]. The main phase of fighting occurred between September 16 and 27, 1970 [9]. By summer 1971, all Palestinian forces had been expelled from Jordan into Lebanon [5]. In response to the expulsions, the Black September Organization (BSO), a militant faction, was founded in 1971 to carry out retaliatory attacks, most notably the assassination of Jordanian Prime Minister Wasfi Tal [1, 4, 8]. The role of external actors, such as Pakistani General Zia-ul-Haq, in assisting the Jordanian military during the conflict is also a subject of contested claims [14, 15].

STRONGEST CASE FOR

The Black September conflict was a necessary response by the Jordanian monarchy to maintain sovereignty and prevent a state within a state, as the PLO's growing military and political power posed a direct threat to the stability of Jordan. King Hussein's actions, supported by his intelligence services, were aimed at defending the Hashemite monarchy and protecting Jordanian national interests against an armed group attempting to seize power. The expulsion of Palestinian forces, while tragic, was a consequence of the PLO's aggressive actions and their attempts to overthrow the government.

STRONGEST CASE AGAINST

The Black September conflict represented a brutal suppression of the Palestinian resistance movement and a massacre of Palestinian refugees by the Jordanian government, supported by external forces. The actions taken by King Hussein led to the deaths of thousands of Palestinians and their forced displacement, further exacerbating their plight as refugees. The narrative of the PLO as solely aggressors seeking to overthrow the monarchy minimizes the legitimate grievances and aspirations of Palestinians living in Jordan and the violence they faced.
