Vito Genovese wanted to take over the crime family led by Frank Costello. CrimeLibray.com said this: Moretti's Jersey boys also provided the muscle behind Costello, and eliminating Moretti would weaken Costello.

But why does the head of the Luciano(later Genovese)-family need a Willie Moretti who only has 50-60 buttonmen? The Genovese crime family was the most powereful (and largest?) crime Family in the US, so why needed Frank an ally? I mean Frank's family was far more powerfull than Moretti's..wasn't it?

'This was just another Bronx tale.'
