In other words, June 9, 1972 john kerry was active with VVAW. Also June 9, 1972, this document was written stating that recently the VVAW supplied NVN with details about our military plans and capabilities, as provided by active duty soldiers. Have we figured out who delivered the information? It would be interesting if it coincided with a Paris trip by kerry.
So they didn't need to go all the way to Paris.
Also, some of the VVAW leaders travled to Moscow.
KGB link.
