I was disappointed too, but don't think it's a big deal. Eventually, the truth of the matter will come out. Not everything needs to be promptly corrected. Look at the interval between "no Swiftee was on Kerry's boat" to the revelation of Gardner.
Now Kerry said he was on a "secret mission" there, under the LBJ administration, when Cambodia was a "neutral" country and we shouldn't have been there.
Later, I believe in 1970, Nixon gave the order to go into Cambodia and clean up the Communist military refuges that had been giving our boys so much trouble. At that time, we then had A LOT of our people in Cambodia, and everyone knew, it wasn't like it was a secret then. In fact, the Kent State protesters were protesting on this when the Ohio National Guard opened fire on them.
Anyway, doesn't anyone in the MSM see a big difference from Kerry's unsubstantiated admission to being there and O'Neill's when O'Neill's happened as part of an invasion? Or was O'Neill's statement to Nixon BEFORE we went in in force?
