The late Howard Zinn, an important 20th century figure, endorses Petros' work in a e-mail dated June 21 2009:
I finally got around to reading your manuscript, and I must say I am very impressed. with the substance of what you say, and also the way you write. You present a very thoughtful, indeed profound analysis of our present situation, of this time in history, of "the cult of corrporatism" and esecially of pharmaceutical comporations. You research on the "bird flu " is mind-opening .and you connect evrything with the monstrous threat of biological warfare .
Thanks for lettting me read this. I certainly admie your writing style, which is lively and compelling.
