Pakistan played a crucial role in the Afghan-Soviet War, acting as a primary conduit for international support to the Mujahideen. Pakistani intelligence agency, the ISI, coordinated the distribution of aid and weapons, much of it supplied by the United States and Saudi Arabia. Pakistan also hosted millions of Afghan refugees fleeing the conflict. In the war's aftermath, Pakistan continued to exert significant influence in Afghanistan, supporting various Afghan factions. Its policies, particularly its support for certain groups, helped shape the post-war political landscape in Afghanistan, including the eventual rise of the Taliban.

The Geneva Accords of 1988, facilitated by the United Nations, aimed to resolve the Afghan conflict by stipulating the withdrawal of Soviet troops and the non-intervention of external powers in Afghanistan's internal affairs. However, the Accords were ultimately unsuccessful in bringing lasting peace. They failed to include key Afghan factions, particularly the Mujahideen, in the negotiations. This oversight meant that while the Soviet Union withdrew, the internal power struggle in Afghanistan continued unabated, leading to further civil war. The lack of a comprehensive political solution and the continued external support for various factions also undermined the Accords' effectiveness.

The Afghan-Soviet War had profound effects on the regional dynamics in South Asia and the Middle East. It heightened geopolitical tensions and stimulated an arms race in the region. The conflict drew in regional powers like Iran and Pakistan, each supporting different factions in Afghanistan for their strategic interests. The presence of Soviet forces so close to the Persian Gulf alarmed many Middle Eastern countries, leading to closer ties between these nations and the West, particularly the U.S. The war also led to significant refugee flows, particularly into Pakistan and Iran, which had lasting social and economic impacts on these countries.

The Soviet invasion of Afghanistan played a significant role in the eventual dissolution of the Soviet Union. The protracted conflict drained Soviet resources and finances, exacerbated by the global drop in oil prices, which was crucial for the Soviet economy. The war also contributed to internal dissent and loss of faith in the government, particularly as casualties mounted and the purpose of the war became increasingly unclear to the Soviet public. Furthermore, the Afghan War undermined Soviet authority in the Eastern Bloc, signalling vulnerability and encouraging independence movements, eventually contributing to the fall of the USSR.

Operation Cyclone was a CIA-led initiative aimed at supporting the Afghan Mujahideen in their fight against the Soviet occupation. Its main objectives included providing financial support, intelligence, and military equipment, notably anti-aircraft weapons like the Stinger missile. This operation significantly impacted the Afghan-Soviet War by enhancing the Mujahideen's capabilities, allowing them to effectively challenge Soviet air superiority and inflict heavier casualties. It marked a key shift in the war's dynamics, turning it into a costly quagmire for the Soviet Union and contributing to their eventual withdrawal.
