Why did osama bin laden declared war on the united states open study?

Exactly two decades ago, on August 23, 1996, Osama bin Laden declared war on the United States. At the time, few people paid much attention. But it was the start of what’s now the Twenty Years’ War between the United States and al-Qaeda-a conflict that both sides have ultimately lost.

During the 1980s, bin Laden fought alongside the mujahideen in Afghanistan against the Soviet Union. After the Soviets withdrew, he went home to Saudi Arabia, then moved to Sudan before being expelled and returning to Afghanistan in 1996 to live under Taliban protection. Within a few months of his arrival, he issued a 30-page fatwa, "Declaration of War Against the Americans Occupying the Land of the Two Holy Places," which was published in a London-based newspaper, Al-Quds Al-Arabi, and faxed to supporters around the world. It was bin Laden’s first public call for a global jihad against the United States. In a rambling text, bin Laden opined on Islamic history, celebrated recent attacks against U. S. forces in Lebanon and Somalia, and recounted a multitude of grievances against the United States, Israel, and their allies. "The people of Islam had suffered from aggression, iniquity and injustice imposed on them by the Jewish-Christian alliance and their collaborators," he wrote.
