Maybe the Christians Arabs feel more secure in Israel.

If you look in many, if not most, Muslim nations, basically Christians are classified as 2nd class citizens.

Turkey- Christmas Carols banned 
Iraq - Christian population reduced by 2/3rds since Saddam left
Nigeria- Christians & even some Muslims are killed or kidnapped
Sudan - More killing
Algeria -   "
Pakistan - Blasphemy charges resulting in death, with or without a trial
Indonesia - Christian official charged with blasphemy
Palestine - Pension to family for "martyr", among other things.

When Gaza was returned to the Palestinians, I seen a video (CNN?), showing the Palestinians destroying the irrigation systems put in by Israelis. These were high efficient food production systems, that if been used, would have benefited the Palestinians.

Sounds more like many would like to have the Mid-east for Muslims only. And many leaders, hold power, by venting the culture of Jewish, & Christian hate, is to harp on Israel.
