But, how would the people who developed the spray and ordered the spraying protect their own families.
It's true that it'd be easy to tell a pilot that he was spraying one thing and give him another. But, why destroy the world and how would that be accomplished without destroying China and India? Are the people ordering the spraying Americans? Are they starting with the US, their own country, for any particular reason? Who's gonna be left to spray China? Otoh, if it's about destroying the US, or destroying its weather, then, ok, investors in Home Depot might delight in more hurricanes and tornadoes. I tend to doubt that "the gov't" is doing it, and I can't think of any specific American group with the desire or resources to accomplish their evil goals through chemtrails. If there were such a group, I think they'd be furriners.
