Why did osoma laden declare war on the united states

Osama bin laden's proclamation of the sacred battle against these United States, and the 1998 fatwā contracted by bin Laden and others, shouting for this kill of Americans, are seen by investigators as evidence of his motivation. At bin laden's Nov 2002 "text to U.S. S," he expressly said that al-Qaeda's motivations for their attacks include: Bin Laden represented Mohammed as having censored that "permanent presence of infidels in Arabia." In 1996, bin Laden released the fatwā line for American forces to leave Saudi Arabia. At 1998, al-Qaeda published, "for around seven periods this United States has represented invading these kingdoms of religion at this holiest of spaces, this Arab land, plundering its riches, dictating to its rulers, humiliating its people, terrorizing its neighbors, and turning its bases in the Peninsula into a spearhead through which to fight the neighboring Muslim peoples.
