You're second link about appointing Jimmy Blue Eyes as Doto's replacement? Look at the members of that meeting.......Jimmy Blue eyes, trigger mike coppola, joey rao, meyer lansky, benny levine, tommy milo, lefty clark, and ben novak. Now do you think Lansky, levine, clark, and novak were there to discuss who takes over positions in the Italian mafia? No. Considering the attendees it was obviously just to straighten out affairs in Florida, mainly Miami Beach.
Two things being slightly confused here. The 52/53 meeting was to do with Jimmy Blue Eyes taking over from Costello as Syndicate boss, ie: Gambling boss, mainly Miami based as evidenced by the attendees. They were the guys that ran most of the nationwide gambling operations. Casinos and sports betting mainly.
The reports of Alo taking over from Adonis were to do with him replacing him as capo in 56 after Adonis was deported. I suspect he was capo before that with his own Bronx based crew and simply took over some of Adonis more lucrative rackets along with some of Joey A's men.
