Of course. Kerry's used to surrendering.
A major theme of the Vietnam Veterans Against the War (VVAW) in 1971 involved sending representatives to Paris and to Hanoi to meet with communist leaders. John Kerry has admitted to meeting in 1970 in Paris with Madame Nguyen Thi Binh, the Foreign Minister of the Provisional Revolutionary Government, the "waiting-in-the-wings government" ready to take over South Vietnam once the Communists won. Kerry was still in the Navy at that time.
