Actually, the Donnie Brasco operation didn't do very much damage to the Bonannos, except hurt their reputation severely and got them kicked off the Commission. Virtually no one got very much time in the grand scheme of things. If anything getting kicked off the Commission was a boost, it allowed them to dodge a bullet (the Commission Trial) and rebuild in the shadows. Massino was actually a pretty successful boss when you consider that he lasted over a decade in post-RICO times, into the 21st century, you know, times when most people are saying is no longer possible to last that long. The public for the most part thinks that the Mafia died with John Gotti yet here we are with bosses that came afterwards outlasting him. Virtually everyone's heard of Capone and Gotti, guarantee you the vast, vast, majority of people never heard of Massino, Bellomo or Mannino.

Something else, why is Massino considered the 1st and only American Mafia don to ever flip? Frank Salemme, boss of the Patriarca Family, flipped before he did.
