To be fair they didn't give us any of that stuff it already existed and many companies produced it or it is a chemical byproduct.
They didn't discover or invent any of them.
When you read misleading stories it makes me question everything in it.
As a matter of fact you dont manufacture buy agent orange you mix 2-4-D and 2-4-5-T at 50-50 to get it.
2-4-5 T is the culprit that causes problems and is not manufactured.
