The Nigerian groups are a smart bunch. They willfully limit their role to that of "transporters". There's basically zero violence associated with them - except for a few cases in Europe involving petty small time drug dealers who happened to be of a Nigerian background. They appear to have zero interest in "territory". They bring the product, get paid, and everything after is handled by traditional OC groups (mobs, gangs...).
yes, but it is what all criminal groups usually do outside their territories, it's what italian and russian mafia does in spain for example, or albanians in italy
only where you have some neighborhoods in your hands you can control territories like arabs in france, at least drug trade
if you have not at least a neighborhood you cant do so much, just that
italian mafia in the states had control of territories since the beginning, but the target of italian mafias is that, not only drug or illegal activities, it's coz ndrangheta infiltrated several north italian zones
