Few recent UFO books in my library have made significant contribution to the field, but this one sure did. There's so much conspiracy theory out there that you could spend years exploring it, but Salla draws it all together into focus, all the while keeping in mind the question, "What exactly does it take to convince a jury?" But wait, there's more!
Salla's book is multi-faceted. It's a political analysis AND a conspiracy theory. Whilst most researchers might be tempted to enter into endless phylosophical political debate, Salla approaches his thesis by building a framework on the assumption that, since there has already been a long standing ET presence, we already have an exopolitcal relationship - a very dubious and clandestine relationship - one that desperately needs to be exposed before mankind can move forward.
Salla reviews all the major conspiracy theories, not because he beleives them, but because that's what an impartial scientific person does. He rates his sources, so you don't have to, and confesses that, although one particular source might not seem reliable, it's the volume of corroborating sources that gives credence. Salla explores many recent major world events in the context of the ET presence, and some of it, such as the Iraq-Stargate connection, is completely new to me, and he draws it all together into one concise volume, with loads of references for the curious.
Salla admits that his book is far from complete or perfect, but it's a foundation stone and it's a great starting point for bigger things to come. I thought some of the chapters needed some editing for typographical errors or some updating, and the language was a little "dry", but the book is otherwise brilliant.
