The major contention of this documentary made by anti-War World group Tanker Enemy is that The Weather or The Sky has been manipulated in various chemical and electromagnetic ways to look like NATURAL DISASTERS ARE KILLING OFF THOUSANDS OF PEOPLE each event, and that this activity has been UN-sponsored since 1966. The producers of this documentary suggest that this is the role of these so-called chemtrails, "To evoke natural slaughter and deterioration of the human species on a massive scale." Global. Worldwide. Catastrophe.
Check out this Italian documentary Chemtrails, The Secret War. Yes it has subtitles. Deal with that. It's a cracker.
