Nah, the Mafia is still traditional. They won't join with non-Sicilians and seldom associate with non-Italians. They only work with the Jews...or as the late Meyer Lansky once said...the "Kosher" Nostra.
I grew up in Cleveland, and they could have teamed up with the Irish there and made a killing. Instead they blew up Danny Green in his new Buick.........
Big Al HATED the Irish and Polish gangs in Chicago, too. Look what he did to O'Bannion, Weiss, and Moran.
Well then, (as certain US federal agencies might be inclined to do), let's get them aboard and with the "program"! :-)
