i say the domino principle be an enormously underappreciated film . anyone who have take the time to investigate our contemporary history of conspiracy while jfk and rfk and mlk and g. wallace and in fact numerous others can only draw the conclusion that the author of the domino principle really know what he be talk about . roy tucker could be lee harvey oswald or james earl ray or sirhan sirhan or arthur bremer maybe even john hinkley or timothy mcveigh . to mention a few . the conspiracy scenario involve spy and big business and political assassination be not really a fiction but an ominous part of our convoluted existential history . god help u and but the domino principle be more fact than fantasy . if this cause a little loss of sleep and maybe it should . do not take my word for it and investigate for yourselves .
