The only relationship between he and the Corelones that we can be sure of is that he was the Corleones oldest friend. Profaci was a friend to the Bonannos. So, there is precedent for such a relationship families.
Yes, but the relationship between the Bonannos and the Profacis wasn't exactly the kind of relationship between the Corleones and let's say the Tattaglias or Barzinis.
Anyway, in part III there's already a Don Cuneo so what's left are the Straccis. I find it suprising that there is at least one thing you agree on with Winegardner.
If I was Tattaglia or Barzini, I would never, ever trust one of my capos who was the godfather of one the children of my biggest enemies. I would have ordered him whacked as a precaution. Or I would have ordered him to prove his loyalty with personally carrying out the hit on Sonny.
