Colin Andrews actually spilled more about the Royal, Prince Charles connection in the Veritas interview last week but this Red Ice expose is just as excellent for spilling the beans on military shill Nick Pope who is taking a salary from the army in the form of a pension and is leeching off the UFO talk circuit and playing the misinformation and disinformation game. Colin lays it square in this interview and the only question you need to ask yourself is why does my government lie and lie and lie and lie.
