All I can tell you about is the Israelis I come across. Most everyone is associated with academia or advanced research with a smattering of high-tech-ish private sector jobs. They span the range from very leftist to very rightist and don't seem to share much of anything politically or religiously. I know a Sabra researcher who openly praises Hezbollah and I know his friend who's Likud. Some are here for long term temporary and others are here for good. Since most of their children were reared here they have no particular eagerness to go back to Israel.
