I understand that the "what if" situations are endless...But still, if that quote from the "Mobsters" episode was true, that Coonan and Feathersone seriously expected to be killed at the meeting and gave their bodyguards outside the order to kill every mafioso in the restaurant if they won't return after a certain period of time...If it went that way, with the Gambino and Genovese families beheaded (minus Castellano, Dellacroce, Lombardozzi, Gaggi, Tieri, who else was at the meeting?), would the 5 families have stormed Hell's Kitchen with their "soldiers" (inevitably suffering heavy losses, since the Irish knew their territory and the Italians didn't, it would be like a partisan vs army war, far bloodier than the Colombo conflict in the 90s)?

Don't know though whether the situation was really like that, or did the "Mobsters" episode creators "embellish" the story a little, to increase suspense?
