The State of Israel exists because Muslims (Ottoman Turks) backed the wrong horse (Imperial Germany) in World War I.
The British kicked Muslim ass and conquered Jerusalem and the entire former Ottoman imperial province of Palestine.
A great many former provinces of the old Ottoman Empire were divided-up, disestablished, and absorbed into other old or new countries, in whole or in part.
The former Ottoman province of Palestine was more an administrative creation than anything ethnocentric or representative of a particular 'people'.
Like many of its siblings, the former Ottoman province of Palestine was disestablished, then re-tasked, in order to yield the now-permanent State of Israel.
Re-tasked multiple times... first, as a League of Nations Mandate (1918-1948), then as the new State of Israel (1948).
After seventy years (1948-2018), nobody except a relative handful of Muslim-Arab dense-skulls care enough about it to seriously consider fighting Israel over it.
Muslim-Arabs of the region, outside the boundaries of Eretz Yisrael, know better after several failed attempts.
Egypt is a confused shell of is former self, the Saudis know war is bad for business, Libya is a mess, Iraq is a mess, Syria is in active civil war, and Jordan is far too weak.
The Muslim-Arab countries of the region are in no position to try to force the issue militarily, and will not be for years or decades or generations to come.
There is no Muslim-Arab cavalry coming over the hill to rescue the under-performers content to rot in refugee towns and camps for generations without progress.
It's over... the dissolution of the Ottoman province of Palestine and the establishment and present borders of the State of Israel are a fait accompli.
The slow, methodical, inexorable assimilation of the West Bank continues apace, and nobody cares enough to take military action to stop it.
Once absorbed, the Israelis will turn their attention to Gaza.
Once both have been absorbed, the dream of Eretz Yisrael will be completely realized.
Any Muslim-Arab so-called Palestinian with an ounce of brains will come to this glaringly obvious realization, pack his bags, and move his family out of there.
The Jews have won... the so-called Palestinians have lost... time for the Palestinians to scatter, and build new and happy futures for themselves elsewhere.
As for those silly, simpering types who whine over prohibitions of International Law extant at the time of the founding of the State of Israel, the response is a gleeful "vae victus".
