i don't think you know enough of europe to talk about it...nigerians are not the strongest group in europe as you like to believe, they are maybe among the strongest not european groups, but domestic groups are by far the most powerful over there
I completely agree with you m2w,Russian and Italian mafia are most powerful in Europe if not in the world,because of their close political/freemasonry connections.
@BlackFamily: you are the only one that keeps bringing up Nigerian Organized Crime,they are big drug traffickers,true,but they are nowhere near Italian,Russian,Japanese mafia etc.
