For his 2003 UN case for the invasion of Iraq, Powell notably brought a vial to represent the "less than a teaspoon" of anthrax responsible for shutting down the US Senate in 2001 and compare the amount to the 25,000 liters Iraq allegedly could have acquired.

In particular, many critics have cited the potential for history to repeat itself with US Ambassador to the UN Nikki Haley's December presentation of missile fragments as "undeniable [physical] evidence" of Iran providing arms to Houthi rebels in Yemen.
