Not really sure what you're referring. The US has most definitely sprayed poison all over the place in South America with cocoa plant eradication efforts. Or Agent Orange in South East Asia.

If you mean poison as in disinformation, then you'd be wrong there as well. We literally "bombed" Iraq with pamphlets from airplanes encouraging them to rise up against Suddam and we'd be there to support them; we didn't.

No, the GP means literal poison. Neurotoxin, specifically.
