Understanding HAARP is key to understanding chemtrails. It appears the main thrust of this emerging movement is to ignore the MILITARY aspects of this program, which are fundamental and essential. They refer instead to the slow kill of depopulation by the global elite. Probably true enough, but the chemtrails ionize the atmosphere and therefore make it conductive. This allows for masking of spy planes, all sorts of horrible military activities that are actually destroying earth's ionosphere and exposing us to cosmic harm, destroying protective magnetic belts and so on.
