While I am certainly not a first hand expert, allow me to attempt to explain the Kinahans through my understanding of Irish Republican organizations, and global organized crime, that I received from working at an internship in college through several US intelligence/law enforcement agencies. The source of the Kinahan’s power is not through footsoldiers on the ground, it’s through money. After the Good Friday agreement was signed, the PIRA became split. Those that accepted the agreement had two choices, either disarm and live as civilians, or utilize their talents as criminals and continue their activities, only this time for profit rather than Irish unity (a third group formed which is currently fighting the criminal element, although its suspected that this group is just trying to establish control themselves rather than for any noble purpose of ending drug dealing). The Kinahans were already an established crime family, working in boxing, gambling, and narcotics, but on a much smaller scale than today. When the former republicans joined the Kinahans, they brought with the old IRA smuggling routes not only into Ireland, but into Spain via the ETA, as well as connections to the Irish mob in Boston and New York. As the nineties lead to the Celtic Tiger economy in Ireland, as well as the dawn of the Internet age, the Kinahans control of sports betting (legal and otherwise) was drastically expanded. Through smart investments in legal enterprises, the Kinahans amassed a fortune, and their connections, through the IRA, allowed them to offer distribution of narcotics to Mexican cartels. This distribution allows the Kinahans to purchase drugs at a wholesale cost from the cartels, who have a vested interest in propping up the Kinahans so they can access their distribution networks through Spain and NI. The Kinahans, in turn, can exercise influence by choosing who they sell their drugs to. Since they’re one of the few choices, as a street gang you either have to buy from them, or find your own way to smuggle the drugs you wish to sell, which is outside the realm of possibility for most street level gangs. If the Kinahans ever need muscle inEurope they can just contract it out to Eastern European groups, they don’t need to do it themselves. They maintain control because they’re mutually beneficial to both the Mexicans, who don’t have to worry about distribution, and the street gangs, because they don’t have to worry about supply. So foot soldiers in Europe aren’t necessary.
