It seems to me that you are projecting. The supremacist movement I see is the Zionist one. The Muslims are fighting mostly among themselves. The Zionists are the latter day Nazis. They are holding millions of non-Jews in virtual concentration camps killing thousands of them every year or so.
The arab muslims have no legal or moral claim to the land of Palestine, they did not even want to go there until the Jews from Europe had made the desert fertile again.
As indiginous peoples they have the same claim as the Jews.
Not according to CUSTOMARY INTERNATIONAL LAW they don't, unless you can produce a treaty signed by the LEGAL LAND OWNERS giving the land to the arab muslims.
Something like this will do
Mandate For Palestine - The Legal Aspects of Jewish Rights
“In Palestine as of Right and Not on Sufferance ...”
“When it is asked what is meant by the development of the Jewish National Home in Palestine, it may be answered that it is not the imposition of a Jewish nationality upon the inhabitants of Palestine as a whole, but the further development of the existing Jewish community, with the assistance of Jews in other parts of the world, in order that it may become a centre in which the Jewish people as a whole may take, on grounds of religion and race, an interest and a pride. But in order that this community should have the best prospect of free development and provide a full opportunity for the Jewish people to display its capacities, it is essential that it should know that it is in Palestine as of right and not on sufferance.”
Winston Churchill
British Secretary of State for the Colonies
June 1922
Recognition of the Historical Connection to Palestine
Fifty-one member countries – the entire League of Nations – unanimously declared on July 24, 1922:
“Whereas recognition has been given to the historical connection of the Jewish people with Palestine and to the grounds for reconstituting their national home in that country.”

Unlike nation-states in Europe, modern Lebanese, Jordanian, Syrian, and Iraqi nationalities did not evolve. They were arbitrarily created by colonial powers.
In 1919, in the wake of World War I, England and France as Mandatory (e.g., official administrators and mentors) carved up the former Ottoman Empire, which had collapsed a year earlier, into geographic spheres of influence. This divided the Mideast into new political entities with new names and frontiers.

Territory was divided along map meridians without regard for traditional frontiers (i.e., geographic logic and sustainability) or the ethnic composition of indigenous populations.

The prevailing rationale behind these artificially created states was how they served the imperial and commercial needs of their colonial masters. Iraq and Jordan, for instance, were created as emirates to reward the noble Hashemite family from Saudi Arabia for its loyalty to the British against the Ottoman Turks during World War I, under the leadership of Lawrence of Arabia. Iraq was given to Faisal bin Hussein, son of the sheriff of Mecca, in 1918. To reward his younger brother Abdullah with an emirate, Britain cut away 77 percent of its mandate over Palestine earmarked for the Jews and gave it to Abdullah in 1922, creating the new country of Trans-Jordan or Jordan, as it was later named.
The Arabs’ hatred of the Jewish State has never been strong enough to prevent the bloody rivalries that repeatedly rock the Middle East. These conflicts were evident in the civil wars in Yemen and Lebanon, as well as in the war between Iraq and Iran, in the gassing of countless Kurds in Iraq, and in the killing of Iraqis by Iraqis.
The manner in which European colonial powers carved out political entities with little regard to their ethnic composition not only led to this inter-ethnic violence, but it also encouraged dictatorial rule as the only force capable of holding such entities together.

The exception was Palestine, or Eretz-Israel – the territory between the Jordan River and the Mediterranean Sea, where:
“The Mandatory shall be responsible for placing the country [ Palestine] under such political, administrative and economic conditions as will secure the establishment of the Jewish National Home, as laid down in the preamble, and the development of self-governing institutions, and also for safeguarding the civil and religious rights of all the inhabitants of Palestine, irrespective of race and religion.”
