I'm just wondering, and my answer is yes of course. It would of been more like his real-life counterpart Joey Sodano, and plus he tried to kill Tony! Joey Sodano, like Junior, feels that he doesn't get the respect he deserves for all his years in the Mafia, and he resents the young up-and-comers, like Christopher Moltisanti, who think of respect as an Aretha Franklin song.
Joey Sodano was killed supposedly by Merlino supporters in the Stanfa-Merlino war.
I'm no expert but I would think if this was a real situation, once he gave an order to kill Tony, he would have been terminated. But then again, when you look at other situations (e.g., Casso who killed his attempted executioner, but not the guy behind the hit), it's not that far fetched he wasn't after his power was taken out from under him.
AJ's funniest damned line ever is when Chris tells him nobody will be able to get to Junior, and he responds with Rocco Lampone's line from Godfather 2, "Difficult, not impossible".
"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
