Amen. Sometimes it is useful to just let a guest talk but in this case he really needed to point out the contradictions in Mearsheimer's internal logic and mistakes of fact to really see how strong his arguments really are. Since Lex is A) smart B) Speaks Russian C) Has interviewed people such as Kokin and Fiona Hill he was ideally placed to push back and explore the strengths of M's claims but Lex let us down and just went along mostly unquestioningly. A missed opportunity.
