I wrote about the American mob's gambling enterprises around the world here:

The American Mafia bets on the world and wins big

Gambling has always been the American Mafia’s “bread and butter.” After controlling illicit gambling across the United States, the mob upped the ante by turning Las Vegas into Sin City, a gambler’s paradise. But in true gambling spirit: It was never enough. In the decades that followed the mob expanded abroad and set up casinos across the globe in Cuba, Mexico, the Middle East, Africa, and Europe. As the quote goes, “Always the dollars, always the fuckin’ dollars.”
