Most Voaters are familiar with this story which was outed in Senator Frank Church's Senate hearings in 1975. It's fascinating and it's amazing how many "normals" still have never heard of it which is why it's going to be put up one more time.

If you want to verify this through Wikipedia, feel free but be aware that in addition to all of the "state dept" officials spinning and disinforming, the Pentagon currently has actively working for them just under 30,000 FTE (Full Time Employees) who's job it is to spin what we see and hear.

Makes one wonder what kind of a fantastic price in taxes and psychic energy burned off that citizens pay to have all these lies directed our way.
