When bin Laden left college in 1979, he was already a well established businessman. He went to Pakistan and began using the funds from his construction and machinery company to fund Mujahideen fighters in the Soviet war in Afghanistan. During this time up until 1989 the United States government was also providing the resistance fighters with money and weapons.
Bin Laden founded the ‘Maktab al-Khidamat’, or Afghan Services Bureau, and used this organization to funnel money into Afghanistan to support the Mujahideen. In 1988 he split from the ‘Maktab Al-Knidamat’ and used his flourishing popularity and influences to form the far more militant international terrorist group ‘Al Qaeda’.
The 1990 Iraqi invasion of Kuwait led by Saddam Hussein threatened internal dissent in the kingdom of Saudi Arabia. Bin Laden appealed to the Saudi government to avoid bringing any non-Muslim involvement into this struggle, but they ignored his advice and U.S. forces were deployed in Saudi territory.
He continued to be outspoken against the government's actions until two years later he was banished from his home country. He fled to Sudan and lived in exile.
During his exile in Sudan he continued to speak out against the Saudi government and the U.S. forces in Saudi Arabia, and was also known to be heavily involved with the ‘Egyptian Islamic Jihad’, which was the core of ‘Al Qaeda’.
After the failed EIJ assassination attempt of the Egyptian president, the U.S. accused Sudan of sponsoring international terrorism, which led them to eventually banish bin Laden in 1996, along with his organization.
After his return to Afghanistan, bin Laden declared was against the United States, claiming that the evils of the Middle East were due to American interference. He returned to his roots and enlisted the aid of his associates from the Soviet jihad to help him raise money to sponsor his attacks.
In 1998 bin Laden was placed on the FBI's ten most wanted list for his involvement in the U.S. embassy bombings that killed hundreds of people in multiple major East African cities. By the end of that year American counterterrorist intelligence knew of his plans to hijack aircraft.
Following the infamous September 11 attacks, the FBI found irrefutable classified evidence linking ‘Al Qaeda’ and bin Laden to the hijacking. Although he at first denied his involvement, he admitted that he was behind the attacks in a video released in 2004.
Bin Laden was wanted on multiple accounts of mass murder, terrorism and war crimes in many different nations. In 1998 he was placed on the FBI's ten most wanted list for his involvement in an embassy bombing that killed hundreds.
Osama bin Laden's name is linked with the attack on the World Trade Center on September 11, 2001. At the time of this incident he had been wanted by the FBI for years.
