I still don't understand what it was Fredo thought he was going to do to get Mike to go easy on the "negotiations." It is even more perplexing that Fredo seemed legitimately clueless about the family making an investment with Roth in Havana. What other "negotiations" were going on? It wasnt over the Tropicala because Ola already told Mike that Roth gave the ok to the deal.
