It seems disingenuous for CNN to state that the chemtrails conspiracy theory "falsely asserts the US government used non-existent weather manipulation technology," when the US government does actually have weather manipulation technology that it has used for decades, including offensively during the Vietnam War [1]. I am not claiming that the federal government can control hurricanes, in fact later studies conducted by NOAA seem to point towards this not being physically possible [2] but it seems like a natural thing for someone to be curious about.
