It's an affront to civilisation, and to the ideals of the Jewish state.
In my opinion, Israel, living in peace with its neighbors is an affront to the Muslim belief that Islam never gives up land. When the British left, to the Muslim thinking, the land should have reverted back to an Islamic country.
That is exacerbated by the fact that the movers and shakers of Israel are of European descent, and bring up visions of European colonizing to the Islamic mind, in my opinion.
Jews (and Christians) lived peacefully in the past in Muslim countries, but as second class citizens that owed more tax money.
If we could live into the future centuries, we might see Spain being threatened, since that was once the land of the Moors.
Your claim above, about Israel being an affront to civilization, is so silly when compared to the affront to civilization that the Final Solution was, and other excesses of the Third Reich. So, since Israel is not using slave labor, nor herding anyone into gas chambers, nor burning the bodies in crematoriums, nor making lampshades out of human skin, or soap out of human fat, talking about affronts to civilization just sounds so anti-Semitic, when Israel before 1967 was the source of employment for many Palestinians. Then they got involved with their identity, and the harmony ended. Sort of like the domestics of 19th century Britain starting to resent the lady of the house. It was not their position to take umbrage.
The correct analysis might be simply, this is a sticky wicket.
