The US Army has had tests since the 1960’s at least.
So, why would they lie?
I do not know.
Ignorance? That is the only good answer, because as easy as it is to know the truth, it is scary that reporters would intentionally lie about something like this.
Unless they want US to go to war in Syria?
And that is scarier. IMHO.
Do you think war in Syria is coming?
