"i mean for example medellin and the cali cartel and there arent pretty much organizations in west europe who are similar to the five families even the calabrians come here for a few years then they get screwed pretty fast because they lack manpower."

the sicilian mafia in italy has a similar structure the ny families were formed by sicilians at the end of 1800

"Look at the fall of the U.S mafia families compared to their power in the late 1950's, everything has a beginning and a end, nothing can last forever"

yes but the italian mafia survived more than anyone, it's still present after centuries in italy and more than 1 century in the states
