John Kerry first came to prominence with his unauthorized negotiations with the North Vietnamese to end the Vietnam war. (Since he was still in the Navy at the time this was a punishable offense, and could be construed as traitorous. This activity is probably why he didn't get an honorable discharge until after Carter became President.) Now he is negotiating with the Taliban to end the war in Afghanistan. (That is not the role of Senators, but presumably it is OK with Obama.) Kerry hasn't changed much. He likes capitulating to our enemies.
