Leading to War is a 2008 American documentary film composed entirely of archival news footage of the declarations of the United States President George W. Bush and his administration explaining their reasons to attack Iraq in 2003. The film is presented as a historical record and highlights the rhetorical devices and techniques employed by a government to wage war against another nation.

In addition to the pre-war claims made by the Bush administration as presented in the film, the filmmakers also maintain a website that analyzes the wide-ranging strategies and rhetorical techniques used by the administration in marketing the idea of a war with Iraq. It also tracks the cost of the Iraq War in terms of lives lost, the mentally and physically injured, the number of refugees, and the financial burden.
