I've posted this on other forums as well, but this one is very profound and educational, so I'll post it again. If anyone isn't familiar with the work of Dr. Michael Salla, now is the time. He is one of the founders of the exopolitical movement.
This is from X-Con 2005. He does an amazing job of categorizing the 57 classes of supposedly known ET groups, and their political agendas. Please check this out.
For a more detailed perspective of the exopolitical motivations of ET races, go right to the report from Dr. Michael Salla's website.
This man knows his stuff. I highly recommend ANYTHING you can find on this guy.
