How did America make Al-Qaeda angry during Gulf War?

America made Al-Qaeda angry during the Gulf War primarily by stationing U.S. troops in Saudi Arabia, which is home to Islam's holiest sites. This military presence was seen as an occupation by Osama bin Laden and his followers, who viewed it as a violation of Islamic sovereignty. Additionally, the U.S.-led coalition's actions against Iraq and its support for Israel further fueled resentment among extremists, leading to increased anti-American sentiment and the eventual emergence of Al-Qaeda as a prominent terrorist organization.
