Pakistan tried to install Gulbuddin Hekmatyar in power in Afghanistan against the opposition of all other mujahideen commanders and factions.[26] As early as October 1990, the Inter-Services Intelligence had devised a plan for Hekmatyar to conduct a mass bombardment of the Afghan capital Kabul with possible Pakistani troop enforcements.[26] This unilateral ISI-Hekmatyar plan came although the thirty most important mujahideen commanders had agreed on holding a conference inclusive of all Afghan groups to decide on a common future strategy.[26] Peter Tomsen reports that the protest by the other mujahideen commanders was like a "firestorm".
