We posted the information about Kerry having met with North Vietnamese and PRG (Vietcong) representatives in Paris several days ago on WinterSoldier.com -- see the February 27 link in What's New. It isn't clear to me that Kerry joined the other 2 VVAW representatives on the 1971 trip, however -- he may well have gone earlier, possibly in 1970. Interestingly, Jane Fonda *was* in Paris in March, 1971 and had a private meeting with Madame Bihn of the PRG. (see "Aid and Comfort")
Tying down exactly when Kerry went to Paris and with whom would be rather a valuable piece of information...
Yes. It'd also be worthwhile to crossreference Kerry's Paris contacts with those involved in the Paris peace negotiations during the 1968 campaign. As I recall in 1968 Averell Harriman and Bobby Kennedy were involved in some similar shenanigans trying to undercut LBJ's Vietnam policy by conducting their own negotiations via Paris. Would be interesting to see if any of their Paris contacts linked with Kerry's--especially in light of Kerry's own connection to Ted Kennedy.
