Very much EXCEPTIONS to the rule, RARELY seen, I never saw them myself in the 70's, on returning to the same town I had left decades earlier having moved abroad (returning around 2010) the whole sky was full of persistent chemtrails. Until then I, like you thought chemtrails was a kooky conspiracy theory. I had not become used to their introduction like some boiling frog. I had 2 terms of reference decades apart. Where I live now in Asia, I have only noticed chemtrails here within the past year and I have lived in the same place 20 years, they are still rare here. What I would conclude is that the west ie the Goyim are the main target of these chemtrails.
