Kerry should demand that his ISIS guys start calling him Hanoi Boi.
We should remember that John Kerry's first diplomatic job, long before this U.S. State Dept gig., was as a wartime emissary for North Vietnam and the communist Viet Cong.
He met with their officials in Paris, France (where he was ostensibly on his honeymoon) and then returned to the USA to hammer forth the communists' negotiating points at rallies, in the media, and before congress.
And of course his second diplomatic posting came during his time in the Senate, when he faithfully represented the interests of the Nicaraguan Sandinistas to the U.S. government.
