Lets play hypotheticals and say Big Paul had the chance
To deal with Ruggerio, Carniglia (sp) and Gene Gotti
For dealing in heroin.
Would have demoted all of them along with John Gotti
or would have Paul took a page from the infamous
3 Captains hit and had them plus John Gotti ambushed
I wonder if Paul would have reached out to another family
In helping him with this situation.

No way,if Castellano would order the murders,Gotti,Carneglia and Ruggiero would be dead. Some say that Castellano woulnd not order to kill DeMeo but the truth is that the Gambinos was plenty of killers.

At that time Gigante was handling the killing of killing anyone dealing drugs, if what we read of him is true. He would have killed Gotti. Or, the entire Gotti group would have been cut off by Castellano, to avoid a bloodbath. Ruggiero seems to have been a goner either way. Gotti was able to kill Castellano because he had Locascio and Gravano along with others backing him. If Castellano cuts him off earlier, Castellano live, but spends his remaining years in prison,

I think the key player in the whole scenario was Neil Dallacroce. He was able to stall Castellano from getting the "Ruggiero tapes",which bought the crew some time.
He knew that once Paul heard the recordings,some action would have to be taken. Neil may have figured that he could sitdown with Paul and get Gotti off the hook as far as getting executed,but I agree that Angie would have to go. He was pretty much the sacrifice play.
Bu the same token,I believe that as long as Neil was alive,Gotti would have never dared to make a move on Paul.
Dellacroce would never sanction a non-Commission ordered hit on a sitting Boss.
In fact I think Neil was so old school that if Paul ordered him to hit Gotti,he would have done it,no questions asked.

I think the other key player was DeCicco, as he was really well liked and respected.
Seeing three prominent players line up behind Gotti, was enough for all to pause.

Gravano, Decicco and Joe Gallo....

Two biggest brooklyn crews with the most hitters
Gotti is from Queens
And he took over for Neil, and had basically his whole faction behind him.

This was a perfectly planned and executed, execution and take over of a family.

Yeah, but what did it result in?
All the players you mention were dead, or in jail, within 5 years
Gotti took over a powerhouse of a family that had been run really well by Paul for almost 20 years and he ran it into the ground with his ego by 1992. The Family took a good decade or so to recover from the damage Gotti and co did.

Greedy or not, remote or not, Paul ran a tight ship and the Gambinos were a powerhouse while he was at the helm.

Gotti ruined it all.

. Absolutely

Gotti didn't't ruin it, the mob was on the way out with Castellano set to get life, and Joe N. Gallo getting sent away had nothing to do with Gotti. Same for Gigante and his people. Look at the other families, they all went down, none worse than Massinos people, he picked a bunch of rats as captains and as his underboss. Then he ratted. Gotti had Locascio and a few other good men, and unlike Massino or Casso, Gotti ddi no that after his conviction Gravano hurt the Gambinos, Gotti didn't.
