Wasn't Kerry in Cambodia during this?
Yesterday on Meet the Press, Kerry said he might not have been there exactly on Christmas day, 1968, but it was around then and he had been sent to help the CIA deliver weapons to the Khymer Rouge. And he was there, he had lots of pictures he had taken to prove it, and he had a cap the CIA guy had given him. And even though Nixon was president-elect in Dec. 1968, he apparently was able to authorize the CIA for this mission, although Kerry was very sketchy about the Nixon part.
BTW, if you buy all that I'd really like to talk to you about some prime real estate deals I have.:)
