The PDPA was also never able to rid itself of internal rivalries. Burdened by obvious evidence that the Soviets oversaw its policies, actively dominated the crucial sectors of its government, and literally ran the war, the PDPA could not assert itself as a political force until after the Soviets left. In the civil war period that followed, it gained significant respect, but its internal disputes worsened.

Born divided, the PDPA suffered virtually continuous conflict between its two major factions. The Soviets imposed a public truce upon Parcham and Khalq, but the rivalry continued with hostility and disagreement frequently rising to the surface. Generally, Parcham enjoyed political dominance, while Khalq could not be denied the leverage over the army held by its senior officers. It was a marriage necessary for survival.

Social, linguistic, and regional origins and differing degrees of Marxist radicalism had spurred factionalism from the beginning. When Soviet forces invaded, there was a fifteen-year history of disagreement, dislike, rivalry, violence and murder. Each new episode added further alienation. Events also tended to sub-divide the protagonists. Amin's murder of Taraki divided the Khalqis. Rival military cliques divided the Khalqis further.

Parchamis suffered a series of splits when the Soviets insisted on replacing Karmal with Najibullah as head of the PDPA in 1986. The PDPA was riven by divisions which prevented implementation of policies and compromised its internal security. These fundamental weaknesses were partially masked by the urgency of rallying for common survival in the immediate aftermath of the Soviet withdrawal. Yet, after military successes rifts again began to surface.

        Najibullah's Leadership, 1986-92

Factionalism had a critical impact on the leadership of the PDPA. Najibullah's achievements as a mediator between factions, an effective diplomat, a clever foe, a resourceful administrator and a brilliant spokesman who coped with constant and changing turmoil throughout his six years as head of government, qualified him as a leader among Afghans. His leadership qualities might be summarized as conciliatory authoritarianism: a sure sense of power, how to get it, how to use it, but mediated by willingness to give options to rivals. This combination was glaringly lacking in most of his colleagues and rivals.

Najibullah suffered, to a lesser degree, the same disadvantage that Karmal had when he was installed as General Secretary of the PDPA by the Soviets. Despite Soviet interference and his own frustration and discouragement over the failure to generate substantial popular support, Karmal still had retained enough loyalty within the party to remain in office. This fact was shown by the fierceness of the resistance to Najibullah's appointment within the Parcham faction. This split persisted, forcing Najibullah to straddle his politics between whatever Parchami support he could maintain and alliances he could win from the Khalqis.

Najibullah's reputation was that of a secret police apparatchik with especially effective skills in disengaging Ghilzai and eastern Pushtuns from the resistance. Najibullah was himself a Ghilzai from the large Ahmedzai tribe. His selection by the Soviets was clearly related to his success in running KHAD, the secret police, more effectively than the rest of the DRA had been governed. His appointment thus, was not principally the result of intra-party politics. It was related to crucial changes in the Soviet-Afghan war that would lead to the Soviet military withdrawal.

At the same time a sharp increase in military support for the mujahidin from the United States and Saudi Arabia allowed it to regain the guerilla war initiative. By late August 1986, the first Stinger ground-to-air missiles were used successfully. For nearly a year they would deny the Soviets and the Kabul government effective use of air power.

These shifts in momentum reinforced the inclination of the new Gorbachev government to view further escalation of the war as a misuse of Soviet political and military capital. Such doubts had developed prior to the decision to install Najibullah. In April 1985, one month after Mikhail Gorbachev assumed the Soviet leadership, its May Day greeting to the Kabul government failed to refer to its "revolutionary solidarity" with the PDPA, a signal in Marxist-Leninist rhetoric that their relationship had been downgraded. Several months later, Karmal suggested the inclusion of non-party members in the Revolutionary Council and the promotion of a "mixed economy." These tentative concessions toward non-Marxists won Soviet praise, but divergence in policy became obvious at the Twenty-Seventh Congress of the Communist Party of the Soviet Union in February 1986. Gorbachev's "bleeding wound" speech hinted at a decision to withdraw "in the nearest future." In his own speech Karmal made no reference to withdrawal. In early May he was replaced by Najibullah.

Najibullah was obliged to move toward the evolving Soviet position with great caution. Karmal's followers could use any concessions to non-Marxists or acceptance of a Soviet withdrawal against him. Accordingly, he moved in conflicting directions, insisting there was no room for non-Marxists in government, only offering the possibility of clemency to "bandits" who had been duped by Mujahidin leaders into resisting the government. In addition to air strikes and shelling across the border, KHAD terrorist activity in Pakistan reached its peak under Najibullah.

Late in 1986 Najibullah had stabilized his political position enough to begin matching Moscow's moves toward withdrawal. In September he set up the National Compromise Commission to contact counterrevolutionaries "in order to complete the Saur Revolution in its new phase." Allegedly some 40,000 rebels were contacted. In November Karmal was replaced as now-ceremonial president by a non-party member, Haji Muhammad Samkanai, signaling the PDPA's willingness to open government to non-Marxists.

At the end of 1986 Najibullah unveiled a program of "National Reconciliation." It offered a six-month cease-fire and discussions leading to a possible coalition government in which the PDPA would give up its government monopoly. Contact was to be made with "anti-state armed groups." Affiliation was suggested, allowing resistance forces to retain areas under their control.

In fact much of the substance of the program was happening on the ground in the form of negotiations with disillusioned mujahidin commanders who agreed to cooperate as government militia. The mujahidin leadership rhetorically claimed that the program had no chance for success. For his part Najibullah assured his followers that there would be no compromise over "the accomplishments" of the Saur Revolution. It remained a standoff. While a strenuous propaganda effort was directed at the both the Afghan refugees and Pakistanis in Pakistan's Northwest Frontier Province, the program was essentially a sop to Moscow's hope to tie a favorable political settlement to its desire to pull its forces out.
