Which reason best explains the U.S. decision to go to war with Iraq.

The main reasons provided by the U.S. government for going to war with Iraq in 2003 were the belief that Iraq possessed weapons of mass destruction (WMDs) and posed a threat to national security. Additionally, the U.S. government argued that removing Saddam Hussein from power would lead to a more stable and democratic Iraq, and help in the broader goal of promoting democracy in the region. However, after the invasion, it was later discovered that Iraq did not possess WMDs, leading to criticism and debate about the true motivations for the war.
