Poison gases are being used to trigger a mass die-off of Americans right NOW!
Buildings, residences, apartments, have been prepped and built for this on a mass scale starting at least as early as the 1970s. When building materials were made more porous to accommodate the dispersal of poison gases (& radiation). Poison gas is being piped in & is remotely controlled (valves). Vehicles also equipped with poison gas, starting later about early-mid 2000's.
Many die in their sleep, as the gases are increased or released primarily at night time.
They try to change the set times by abruptly decreasing the real population numbers below 200 million in an attempt to beat their Maker.
