That was around the time the USA dropped a bunch of it on Felluja that left scores of women and children burned to death, you could tell it was WP cos their skin was burned but their clothing was untouched. 


At first they denied it, then they tried to justify it, then they quietly admitted to it a few years later.


 I am sure they could find an alternative for all military uses of WP, anyone claiming to be a civilized military should not be using such barbaric weapons anyway.
