Many thanks Turnbull You are right! I'd forgotten about Roth's best friend, Moe Greene

Tom was slippin' or he belongs to Roth!

Why did Roth “interest himself in an obscure dispute between Pentangeli and the Rosatos over three territories in the Bronx?”
Wonder what 'service' Rosato brothers did, for the 'reward' of the three territories
Was Clemenza's promise binding on Pentangeli? Michael broke the peace made by Vito

“Roth played this one beautifully” wrong footed and lulled Michael – Michael's Tropigala casino take over [Ola's message if Michael moved Klingman out, our friend in Miami will go along] Roth's advocacy of the Rosato brothers, Tahoe shooting, Moe Greene the kid Roth loved and trusted [lost to Michael's bullet in the eye]
Roth's survival in Havana was sheer luck too because of his stroke!
However “always knew Michael was too smart to let any of them beat him” even with slippin' consigliere!

Smart move, brilliantly engineered by Michael, bringing over Frankie Pentangeli's brother, Vincenzo
“what the hell happened here?” voila! Senate hearing collapsed faster than house of cards

Looked it up! Interesting, among others
If it wasn’t for a passing police officer who stopped the attack, Larry Gallo would have been killed

Don Joe Profaci “As a devout Catholic [Say what?!] gave thousands of dollars to Catholic charities”
Corleone foundation Blood money Yeah, right! “It's not personal It's strictly business”

Wonder Luca Brasi was Joseph 'Crazy Joe' Gallo
