i see people mentioning the highway of death when americans committed a bunch of war crimes indiscriminately bombing retreating combatants (a war crime) and non-combatant refugees (also a war crime), but as part of the wanton destruction of infrastructure i think it's worth remembering that the americans also bombed a factory that produced infant formula after running a bunch of news stories claiming it was a chemical weapons plant
