Besides the fact that its almost impossible to determine who is an Expat & who isnt, since almost all have dual citizenship and live at least part of their lives in Israel, There is another problem. Although not relying on any scientific data, just being an ovserver, a lot of Israeli Expats left Israel because they were sick of going to the army and the prospects of having their kids go to the army. Therefore I would hardly say they are Right Wing or they want Israel to go to war. Most have been educated in some of the most elite Liberal schools and have left leaning tenedencies. Tkae Rom Emmnuel for example :)
