I don't know if you had a chance to read this one, but it satates that John Kerry met with hte NV in PAris "before" he became a member of the VVAW. This indicates that he had other communist connections to make that happen.
Also, there is something in here about Kerry beating his wife.
Yes, Kerry visited Paris just before joining the VVAW. He was then working for the Vietnam Moratorium Committee, a group interlocked with the New Mobe, which already had connections to the North Vietnamese Paris delegation and could've facilitated Kerry's contact with them. Kerry may have also had connections through his cousin Brice LaLonde, who in 1968 had become president of a Sorbonne French student union (l'UNEF à la Sorbonne) involved in the Communist-directed French student revolution that year.
