"Arab"-related OC is a Lebanese, North African or Assyrian thing. The Lebanese clans in for instance Germany (or Australia) do seem to regard themselves as Arabs; the North Africans and Assyrians definitely don't. Basically every Moroccan dude I know over here postures himself as a proud Berber and wouldn't pass up on the opportunity to dismiss Arabs as being a "bunch of pansies".

To write them off as a bunch of petty drug dealers is definitely missing the mark a bit. Sure there's plenty of low level rats among them, but there's quite a few who work in the higher regions of the drug trade. Moroccans in for instance Antwerp bring in tons of dope, as do Algerians in for instance the north of Marseille. There's local protection rackets aplenty, prostitution, money laundering... Some of them have definitely moved beyond your average street punk status.

The Assyrians in Detroit had huge mob connections as well. In for instance Sodertalje in Sweden they have formed structures that more or less resemble a local mob outfit. A similar situation is in the southwest of Sydney; where the local street cliques are just farm teams up to do some of the dirty work.

As far as the Lebanese go in Berlin; I feel the Abou-Chakers (the family that has ties to the local rap industry through Bushido) is far from being the most feared or powerful. The Al Zein - Omeirat family has way more pull with branches throughout the whole of Germany as well as international connections. Drugs, extortion, weapons, organized robbery...the whole enchilada. That German series 4 Blocks kinda portrayed them as somewhat cartoonesk criminals that, despite the intimidation tactics, are opposed to murder. Far from the truth as they're definitely not shy to whack someone (the case of Zaki Al Zein for instance).
