Why did the us-led coalition attack Iraq in 2003?

The U.S.-led coalition attacked Iraq in 2003 primarily based on the belief that Saddam Hussein possessed weapons of mass destruction (WMDs) that posed a threat to global security. Additionally, the coalition aimed to remove Hussein from power and promote democracy in the region. The invasion was also framed within the context of the broader "War on Terror" following the September 11 attacks, despite the lack of direct evidence linking Iraq to those attacks. Ultimately, the absence of WMDs post-invasion led to significant controversy and debate over the legitimacy of the war.
