Sparky, I'm kind of mixed, But this DOES open up a whole new method for obtaining the Purple Heart and it's probably not in line with tradition. It does seem tantamount to acknowledging that we allowed enemy infiltrators into our military.
There were rumors of people onboard the USS Tripoli receiving the Purple Heart because we DID hit a mine and we DID breathe in asbestos, paint fumes, chemical fumes,etc. There's no telling what long term effects happened to us as a result of "enemy action". To my knowledge, it was never awarded. (Which is probably the right thing).
