"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.
