The public definitely wanted a war after 9/11. Being anti-war could get you cancelled. https://en.wikipedia.org/wiki/Dixie_Chicks_controversy
Reminded me of the statement that “the U.S. wouldn’t intervene if Iraq invaded Kuwait” 30 years ago. Again only weeks before the invasion that then gave the reason for the first invasion of Iraq by the U.S.
Amazing how often these same tactics work and reliably lead to big sales for the military industrial complex.
