Which U.S. invasion in 2003 aimed to overthrow the regime of Saddam Hussein?

The invasion of Iraq in 2003 that aimed to overthrow Saddam Hussein is known as Operation Iraqi Freedom. This military operation was initiated amid claims that Iraq possessed weapons of mass destruction and was a threat to the United States and its allies. The goal was not only to remove Hussein from power but also to promote democracy in Iraq and stabilize the region.

Operation Enduring Freedom refers to the U.S. campaign against terrorism that began in Afghanistan following the September 11 attacks in 2001, focusing on defeating the Taliban and al-Qaeda. Operation Desert Storm was the combat phase of the Gulf War in 1991, which aimed to expel Iraqi forces from Kuwait. Operation Neptune Spear was the mission that resulted in the death of Osama bin Laden in 2011, unrelated to Iraq. Thus, among the options provided, Operation Iraqi Freedom specifically targets the invasion of Iraq and reflects the stated objective to dismantle Saddam Hussein's regime.
