They don't have to talk about the RF at all.
We have been shown too many pics of H partying by the mainstream media I guess, so ppl forget that he was constantly meeting Heads of States, UN, Diplomats, Activists etc. He would have had to have something to talk about with these ppl. He would have been briefed no doubt just like any other person meeting them. Most of these ppl talk about world problems, solutions etc. Even today, the narrative has been played over so much that ppl who meet them are constantly surprised by how much they know about their organisations and what they stand for.
As for the totem pole of where they stand, well, everyone on that list will tell you where they started, and it was not on the top. Think about it, the Obamas are not doing every engagement in the US, everyday, somebody has to start out somewhere lower.
