Which reason best explains the US decision to go to war with Iraq

There were multiple reasons given by the US government for going to war with Iraq in 2003. Some of the main reasons included:

1. Saddam Hussein's alleged possession of weapons of mass destruction (WMDs) and links to terrorist organizations like Al-Qaeda, posing a threat to the United States and its allies.

2. The goal of regime change in Iraq to remove Saddam Hussein from power and establish a more democratic government.

3. Humanitarian reasons, such as the desire to liberate the Iraqi people from a brutal dictator and improve their quality of life.

4. Geostrategic reasons, including securing access to Iraq's oil reserves and establishing a foothold in the Middle East.

It is ultimately up to individual interpretation as to which reason was the most significant factor in the decision to go to war with Iraq.
