As the war against the Soviets intensified, bin Laden began to adopt a more radical vision. Influenced by extremist scholars and battlefield experiences, he envisioned a transnational jihad that extended beyond Afghanistan. The end of the Soviet-Afghan war in 1989 marked a turning point. Instead of disbanding, many of the foreign fighters sought new causes, and bin Laden capitalized on this by formally establishing al-Qaeda in 1988. Its purpose was clear: to defend Islam from perceived enemies, particularly Western powers and secular regimes in the Middle East.
Throughout the 1990s, al-Qaeda grew in both scope and ambition. Bin Laden’s relocation to Sudan in the early part of the decade offered a temporary safe haven to consolidate his network. During this time, he formed alliances with other militant groups and refined his ideological platform. By the time he returned to Afghanistan in 1996, now under Taliban control, al-Qaeda had developed the infrastructure, funding, and global connections necessary for large-scale operations.
