I can speak for Italy, since I am there on a pretty frequent basis. Italy is mainly being overrun by Africans, not Middle Easterners. There are a ton of Nigerians there, for example...all milling about, many looking for work, but most never finding any. I'll be honest, I don't think they are any more of a threat of danger than the tons of gypsies in Italy, to be honest. The Italians don't want them, but pretend to be nice and tolerate them, I guess hoping they'll eventually go away. No one hires them, because no one wants them sticking around. So a lot of them end up selling drugs and/or doing drugs and then causing violent disturbances in the streets. They seem to be more of an issue in big cities. In the small towns you might see a few wandering around, but I have not seen them causing problems there.
