This leads to another question. By giving the Rosato brothers the green light to kill Frankie, was Roth sending Michael a message that he knew Michael really suspected Roth, and that one way or another Roth would get him?
When Michael met with Roth in Miami, he concluded, "Frank Pentangeli is a dead man." Heh-heh--Roth thought his ploy to make Frankie the patsy for the Tahoe shooting worked. But, instead, Michael dispatched Frankie to settle with the Rosatos. That told Roth that Michael didn't blame Frankie for the Tahoe shooting--meaning that Michael might suspect Roth. But by that time, Roth already had, or was about to have, Michael in Havana, where he'd be assassinated. By ordering the Rosatos kill Frankie, Roth figured he'd eliminate a strong Michael ally and put the Rosatos in place to run the olive oil business.
That raises a question: why would Roth agree to let Michael move Klingman out?
Another way to pacify Michael to buy time while Roth figured out a way to kill him. I think Michael floated the idea of moving Klingman out well before Johnny Ola's meeting with him. The spiel Ola gave Michael was FFC's way of putting us in the picture. At that point, according to Roth's plan, Michael was only hours away from meeting his maker. So, all of that good stuff--"But if you want to move Klingman out, our friend from Miami won't object" (said in front of Rocco and Neri)--was designed to help establish an alibi for Ola and Roth after Michael was whacked: Why would dear, fatherly Roth want to harm the guy whom he just blessed with Klingman's piece of his hotel? It was the same ploy Roth used in Havana--promising Michael his Cuban empire in front of witnesses, so that when he turned up dead, Roth would seemingly have had no motivation to want him killed.
