Three days after the US election results were released, the parties reconvened in Geneva and within the week had agreed to a phased Cuban withdrawal over the course of twenty seven months. In exchange, South Africa pledged to begin bestowing independence on South West Africa by 1 November 1989. On 13 December, South Africa, Angola, and Cuba signed the Brazzaville Protocol, which affirmed their commitment to these conditions and set up a Joint Military Monitoring Commission (JMMC) to supervise the disengagement in Angola. The JMMC was to include Soviet and US observers. All hostilities between the belligerents, including PLAN, were to formally cease by 1 April 1989. On 22 December, the Brazzaville Protocol was enshrined in the Tripartite Accord, which required the SADF to withdraw from Angola and reduce its troop levels in South West Africa to a token force of 1,500 within twelve weeks. Simultaneously, all Cuban brigades would be withdrawn from the border to an area north of the 15th parallel. At least 3,000 Cuban military personnel would depart Angola by April 1989, with another 25,000 leaving within the next six months. The remaining troops would depart at a date not later than 1 July 1991. An additional condition was that South Africa would cease all support for UNITA, and Angola likewise for PLAN and MK.
