to Pakistan during 1983–87 at a cost of $1.2 billion outside the assistance package. The second six-year assistance package (1987–93) amounted to $4.2 billion. Out of this, $2.28 billion were allocated for economic assistance in the form of grants or loan that carried the interest rate of 2–3 per cent. The rest of the allocation ($1.74 billion) was in the form of credit for military purchases. In total, the combined U.S., Saudi, and Chinese aid to the mujahideen is valued at between $6–12 billion. The mujahideen benefited from expanded foreign military support from the United States, Saudi Arabia, Pakistan, United Kingdom and other Muslim nations. Saudi Arabia in particular agreed to match dollar for dollar the money the CIA was sending to the Mujahideen. When Saudi payments were late, Wilson and Avrakotos would fly to Saudi Arabia to persuade the monarchy to fulfill its commitments. Levels of support to the various Afghan factions varied. The ISI tended to favor vigorous Islamists like Hekmatyar's Hezb-e Islami Gulbuddin and Haqqani. Some Americans agreed. However, others favored the relative moderates like Ahmed Shah Massoud. These included two Heritage Foundation foreign policy analysts, Michael Johns and James A. Phillips, both of whom championed Massoud as the Afghan resistance leader most worthy of US support under the Reagan Doctrine. Britain's support Britain's MI6 supported one of the hardline Islamic groups commanded by Ahmad Shah Massoud, who they saw as an effective fighter. Despite the CIA's doubts about Massoud, he became a key MI6 ally; MI6 sent an annual mission of two of their officers as well as military instructors to Massoud and his fighters. Of the weapons given covertly - most were old British army Lee Enfields, some of which were purchased from Indian Army stocks, which proved popular amongst the Afghan resistance groups. Limpet mines, explosives, radios, intelligence, and around fifty Blowpipe Missile launchers with 300 Missiles were sent to the Afghan resistance. The Special Air Service meanwhile gave the resistance vital training inside and outside of Afghanistan. Aftermath After the withdrawal of Soviet troops, the U.S. shifted its interest from Afghanistan. American funding of Hekmatyar and his Hezb-i-Islami party was cut off immediately. In October 1990, U.S. President George H. W. Bush refused to certify that Pakistan did not possess a nuclear explosive device, triggering the imposition of sanctions against Pakistan under the Pressler Amendment (1985) to the Foreign Assistance Act (1961).
