I've always seen Israel as a tiny state besieged on all sides by angry arabs who now think the world owes them the entire planet for some reason.
I think the land masses is few percent for the Israelis and the rest arab.
Another view is that the Jews emigrated to Palestine, which was under British control for several decades, against the wishes of the predominantly Arab population, and then declared an independent state, against the wishes of the Arabs in Palestine and elsewhere.
The Jewish presence in Palestine (now Israel) stretches back much further than that. Received wisdom is that the Jews originated in the time of Abraham - as early as 2000BC - in Mesopotamia (Iraq), and then migrated to Canaan (Israel) in Old Testament times. There is also, of course, the biblical story of the Jews being led from slavery in Egypt, across the Red Sea, to Canaan.
So Canaan/Palestine/Israel has been their homeland for millenia, long before the 'religion of peace' was even a twinkle in some b*gger's eye. Israel is, therefore, a very logical place in which to establish their modern-day homeland - assuming that they, like every other race on this planet, deserves one!
Naturally, all of the surrounding arab states would like to over-run Israel and make it another arab state, but then isn't the proclaimed intention of muslims to take over the entire world?
In ~1900 the Jewish presence in the area was tiny, the vast majority of the inhabitants being Arabs. When Britain was handed the Mandate of Palestine in ~1918 we allowed in Jews en masse, against the professed wishes of the majority Arab population. We tried to reduce immigration later. But post 1945 there were huge numbers entering, for obvious reasons.
I was not under the impression that if your ancestors lived in an area hundreds or thousands of years ago, that gave you a right to the land. Maybe the 'celts' should expel the English back to Northern Europe? They could do that following your reasoning. My parents used to live in a nice house in Leicester. Does that give me a right to that house?
The truth is that Jews suffered persecution for thousands of years, the Holocaust being the most extreme example. And post 1945 European countries saw 'Israel' as a way to rid itself of the Jewish problem. Even after the end of WW2, there were pogroms in Eastern Europe. Poles and others often helped the Nazis and profited from the expulsions/murders of Jews. And lots of countries felt sorry for the Jews. So non Arab countries voted for the establishment of Israel, against the wishes of the Arabs. It is hardly surprising the Arabs feel an injustice was committed, because one was. Both the Jews and the Arabs have suffered.
The problem is how to square the circle. Many Arabs were expelled from Israel. Many Jews were expelled from Europe, and Arab countries. Many Jews know Israel as their birth place, it is their home.
It is a bloody mess.
