Afghan Civil War (1989–1992)
The Hezb-e Islami group was led by Gulbuddin Hekmatyar. This party was mainly supported by the Pakistani Inter-Services Intelligence (ISI). Because American assistance to the mujahideen flowed through Pakistan, the Hezb-e Islami group received a lot of money. Because of this, the party was able to grow stronger and become one of the main mujahideen groups in the fight against Najibullah. However, they were not able to defeat Najibullah immediately after the Soviets left Afghanistan. This happened because the United States thought that Najibullah's regime would collapse under pressure by the mujahideen after the Soviets left, so they stopped giving them financial and military assistance. However, Najibullah's regime was able to stay in power because of Soviet support, allowing them to keep the Hezb-e Islami party under control.
