Luciano - Genovese
The tension between Charles Luciano and Vito Genovese reached a boiling point at the conclusion of the Havana Conference. In Luciano's room, Vito told him that the U.S. government knew that Lucky was in Cuba, and was putting pressure on the Batista regime to have him expelled. Genovese then declared his desire to inherit Lucky's holdings, since Luciano would be back in Italy.

Luciano snapped, sure that Vito had tipped off the Washington authorities about his whereabouts. He proceeded to beat Genovese and eventually broke three of his ribs; it was three days before Vito could travel again. Luciano and Albert Anastasia then put Genovese on a plane and Charlie Luciano threatened Vito Genovese with death if he ever mentioned the altercation to anyone.

In February 1947, the New York City papers got wind of the fact that Lucky was in Cuba, and U.S. drug agent Harry Anslinger or Asslinger as Luciano called him, demanded that Charlie "Lucky" Luciano be deported back to Italy. Anslinger even went so far as to seek support for Luciano's expulsion from President Harry S. Truman when the Cuban government refused to comply with his request. The U.S. government halted all shipments of medical supplies to Cuba until Luciano left; Lucky, Lansky, and Batista tried to concoct a counter to this embargo by trying to halt all Cuban sugar shipments to the U.S., but it failed. Luciano was arrested that month, and arrested again once he landed on Italian soil in April.

This is interesting as the rule of not laying hands on another made man vito was a snake and had contacts in intelligence luciano shoulda killed him

Luciano effectively did kill him as it was him and Lansky? who set Vito up via a drugs deal and sent him to prison(1959), Vito's health went down hill and he died of a heart attack in jail in 1969..
