Two things wrong with that claim: (1) There is no longer such a thing as "Palestinian," and (2) the "illegal occupiers" of the "territories"--Judea (Yehuda)*, Samaria (Shomron)**, and Gaza (Asa)***--are Moslem Arabs, not Israeli Jews.
"Palestine" (Palaestina) was a name given to Judea (Yehuda) by the Romans to humiliate the Jews (Judeans, Yehudim) by calling their depopulated land by the name of their ancient enemy, the Philistines (pleshti). ****
The Moslem Arabs who today claim the name of "Palestinians" were created by the despicable Egyptian sodomist Arafat. As has been stated since times immemorial, the people first called "Palestinians" were the Jews that had remained and returned to the Turkish-ruled "Palestine" and the British-ruled Mandate of "Palestine."
The Moslem-Arabs that were the remnants of the Moslem-Arab invasion of Byzantine Greek-held Judea, Samaria, and Gaza, were simply referred to as "Arabs." That is what they were not descendants of ancient pleshti (non-semitic "sea people" thought to have come to the area from the Greek archipelago).
Of course this population contains arabized, moslemized people of different strains that at the time of the "Palestine" Mandate considered themselves to be Arabs and Moslems (yes, with Christian Arabs amongst them--some of them more Arab than Christian, others as Jew-hating as the Moslem Arabs, and some aware of their status as "subhuman" (dhimmis) under Moslem rule who realized that the Jews did not relegate them to that inferior status.)
Now, as far as the territory that was intended for Jews and a Jewish homeland by the League of Nations Mandate--which is now occupied by Arab late-comers and interlopers--the land that includes Judea, Samaria, and the given-over-to-the-savages Gaza, it was to have been part of that Jewish homeland--the Jewish State of Israel (a Jewish State, where only Jews should have been granted citizenship, with residence allowed for non-Jews that held no ill-will towards Jews, and expulsion of Jew-haters of any stripe--a country for Jews to seek refuge from a mostly Jew-hating world.)
These territories "occupied" now by Moslem Arabs include Judea, Samaria and the lately "Moslem-Arab occupied" Gaza. No matter what Roman Latin and Moslem-Arab names given to Judea, Samaria, and Gaza, these are the ancient lands of the Jews.
The sniveling, shedding-tears-for-murderous-and-murdering-Arab-Moslems representatives of the nations--be they from Scandinavia, Italy, or Islamic-Turkey--the TIPH (Temporary International Presence in Hebron), have replaced the Arab-against-Jews-supporting unlamented British of the Mandate, except that they go about armed with anti-Israel propaganda weapons instead of immediately lethal arms and laws, and the Jew-crushing former occupiers of the ancient lands of the Jews, the Turks, Byzantines, Arab-Moslems from Arabia, and Romans.
* Judea - 1. Roman name of the ancient kingdom of the Jews, Yehuda (Judah).
2. The area that roughly corresponds to a part of that kingdom, part of which is in the southern part of the West Bank of the Jordan, including Hebron and Jericho.
In Herod's time, the Kingdom of Judea encompassed all of the area of Jewish sovereignty, including Gaza.
The name Jew derives from Yehuda (Judah)
"Israel is the very embodiment of Jewish continuity: It is the only nation on earth that inhabits the same land, bears the same name, speaks the same language, and worships the same God that it did 3,000 years ago. You dig the soil and you find pottery from Davidic times, coins from Bar Kokhba, and 2,000-year-old scrolls written in a script remarkably like the one that today advertises ice cream at the corner candy store."

Ingathering of the Israelites
Quote from Charles Krauthammer - The Weekly Standard, May 11, 1998
** "Shomron is the heart of Biblical Israel. Most of today's communities were built near ancient sites from the First and Second Temples periods, and the time of the Mishna and the Talmud." See http://www.magniel.com/shomron/ especially http://www.magniel.com/shomron/geo.html
*** The current occupiers of most of Gaza/Aza today are the Arabs/Moslems. But they are not the descendants of the original inhabitants. Gaza/Aza is mentioned 18 times in The Bible as part of the Jewish homeland. The Israelites had been in Gaza before the time of Samson (Judges, 16:1) and were still in possession of it in the time of Solomon (Kings I:4:1). (6) However, just as what happened in Judea and Samaria, Gaza/Aza had its Jews expelled, and has been occupied by numerous invaders and foreign civilizations.
Gaza/Aza was part of the Jewish homeland long before Islam sprang into being. Archeologists have documented remains of a Roman-period synagogue in Gaza which includes Judaic inscriptions on a column located today in the major mosque of Gaza/Aza. This writing is a Hebrew-Greek inscription complete with Jewish motifs that mention Hananiah, the son of Jacob. It has been dated to the second or third centuries -- long before Mohammed lived.

Who Are The Palestinians?
by Yashiko Sagamori, MiddleEastFacts.com
QUOTE from a "Palestinian" (born in Egypt):
"We Palestinians will take over everything, including all of Jerusalem....All the rich Jews who will get compensation will travel to America....We of the PLO will now concentrate all our efforts on splitting Israel psychologically into two camps. Within five years we will have six to seven million Arabs living in the West Bank and in Jerusalem....You understand that we plan to eliminate the State of Israel and establish a purely Palestinian State....I have no use for Jews; they are and remain Jews."Yasser Arafat - Palestinian 'President', Jan. 30, 1996, Private speech to Arab leaders - "The Impending Total Collapse of Israel", Stockholm, Sweden More Quotes
