1. From 1980-1991, Saddam Hussein led Iraq in the devastating Iran-Iraq War and later invaded and annexed Kuwait, leading the US to spearhead a coalition that drove Iraqi forces out of Kuwait in Operation Desert Storm. However, President H.W. Bush decided not to remove Saddam from power, a decision that would be debated.
2. In the early 2000s, the US invaded Iraq again due to suspicions that Saddam possessed weapons of mass destruction and posed a terrorist threat, though no WMDs were found. This second Iraq War led to a costly US occupation aimed at establishing democracy but resulted in sectarian violence between Shiite and Sunni groups.
