Donald Rumsfeld, then US Secretary of Defense, spoke at the Pentagon on 10 September 2001. He said some estimates showed his department could not track $2.3 trillion (about £1.7 trillion) in transactions. An X account that retells that year's news day by day has drawn 2.6M views with a clip of the speech.
A caption on the clip called the sum 'unaccounted for', but Rumsfeld meant untraceable records, not missing cash. Twenty-five years on, the Pentagon has never passed a full audit. Nobody can confirm its taxpayer-funded books are right. Its watchdog, the Inspector General, found $850B (about £631B) of unproven book changes in six months of 2025.
