Oh wow dude, you really blew my mind. All I read about history was in HS history books, and how George Washington chopped down the cherry tree and Lincoln was born in a log cabin.
Fuck you, condescending asshole.
Now for your theory, let me first say that I would buy this for every conspiracy theorist in the world if I could:
Lets say everything you said about cloud spraying is true. Everything, I mean every single damn detail. Now consider the manpower it would take to do all this? Consider the lack of humanity it would take a person to fly up in the sky and spray hazardous material over his own countrymen? You are trying to tell me that through all of this massively complex operation, not one guy, would feel bad about this? It just won't happen, it is simply too complex.
