Hello Hajj Sameer,
Please see the answer from contributor TNO.
I would like to answer the part of the Asker's question referring to: "Palestine" / "Palestinian refugees":
The Asker describes the land of Israel by falsely-using the term: "Palestine":
Using the term “Palestine” to refer to the land of Israel is misleading, since there has never been any sovereign state of “Palestine” (see below).
The only valid name for the land belongs to the Jewish ‘indigenous” sovereign states before the RE-establishment of Israel in 1948, which are “Israel” or “Judea”.
For example, the Jewish Hasmonean Kingdom of Judea (including the West Bank and Gaza) with its capital at Jerusalem (aka “the Old City” / “East Jerusalem”), and independent as at 110 BCE / 753 BH–752 BH:
http://en.wikipedia.org/wiki/Hasmonean_dynasty
The label “Palestine” historically likely derives from the area much smaller than Israel, referred to in the Bible as “Philistia” (Hebrew: פלשת , Pleshet), within which were the Philistine five city kingdoms, equating approximately to today's Gaza. It was not until well after the disappearance of the Philistines that the Roman occupiers resurrected the term, to impose it on the much larger region of Jewish Judea / Israel.

“After crushing the [Jewish] Bar Kokhba revolt [135 CE / 779 BH–778 BH], the Roman Emperor Hadrian applied [imposed] the name Syria Palestina to the entire region, that had formerly included Judea province.”

Much later in history the League of Nations also resurrected the term “Palestine” from the Roman occupation, this time imposing it on an even larger region.
There has never been a sovereign state of “Palestine” by which the Palestinians could make any claim on the land of Israel. Following the Ottoman Turkish defeat in the First World War, the League of Nations in 1923 authorized a British Mandate resurrecting the name "Palestine" from Roman occupation, to be an administrative region; NOT a sovereign state, an area which included what later would be today’s:
Jordan, Israel, and the Palestinian Territories - On the linked web page please scroll down to its second map:

Under the prior Turkish Ottoman rule, Ottoman-occupied Israel / Judea was simply the Ottoman province of: “Southern Syria”:

The Asker also refers to "Palestinian refugees":
The Palestinians have a unique and false inheritable refugee status from the Arab-dominated United Nations (see further below); a refugee status allowed in no other refugee situation:
https://answersrip.com/question/index?qid=20100215193800AArdJkd
This dishonestly distorts for political bias, both the number of Palestinian refugees / number of alleged "Palestinians", and their claims over “displacement”, and thus cannot be imposed on Israel.
Therefore the Palestinians find it convenient to mislead the world about their true status, by calling many of their towns: “refugee camps” in order to fraudulently tap your international aid money.
The Palestinians obtained their false refugee status from the Arab-dominated United Nations.
U.N. polices are fully-complicit with Palestinian propaganda denying Jewish roots in the land of Israel. The U.N. and its structures have for many years been dominated by a block-vote of up to 56 Arab and additional Islamic-aligned countries (e.g. U.N. member states that are also members of the “Organization of Islamic Cooperation”), plus the influence of Arab oil money; compared to Israel being just one country.
In England a child can inherit a title from its parents and so become a “Lord” or “Lady”. In like manner the pro-Arab U.N. allows Palestinians to inherit “refugee” status; a concept allowed in no other refugee situation.
Israel was Re-established in 1948 following a United Nations Partition Plan which had sought to set up two states, one Jewish and one Arab.
The then Palestinian Jewish Community had accepted the U.N. Partition Plan, while the Palestinian-Arab response was in 1947 to start a civil and terror to oppose the U.N. Partition Plan and instead take ALL the land of Israel, and also to ethnically-cleanse or murder the Jewish population from the Jews ancestral homeland of Israel:
https://en.wikipedia.org/wiki/1947%E2%80%9348_Civil_War_in_Mandatory_Palestine
In 1948 the Arab countries attacked the newly Re-established State of Israel, but the Arabs lost the war. Jordan then occupied the West Bank and East Jerusalem from which the Jordanians expelled the Jews. Egypt occupied the Gaza strip. Neither country offered these areas to the Palestinians.
(Please see the sources which I have put into the “Sources” area of this answer.)
Palestinian propaganda falsely alleges the re-establishment of Israel caused: a “great injustice” / “nakba” (“catastrophe” / “disaster”) to the Palestinians.
In reality:
> The Palestinians violently rejected the Arab state of the United Nations Partition Plan;
> Jordan and Egypt occupied the land proposed for an Arab state under the U.N. Partition Plan (approximating to the West Bank and Gaza);
> BOTH Arabs and Jews, became war-refugees;
> The Palestinians claim falsely with no evidence of any such policy that they were expelled from the land; Jews were indeed expelled by the Arabs as policy. Palestinians live and work in Israel.
Therefore the reader is entitled to be sceptical about Palestinian propaganda falsely alleging a fantasy-injustice.
Whereas:
Pro-Palestinian contributors falsely allege Israeli Jews all came from Europe: The Jewish People have had unbroken presence in their ancestral homeland of Israel since Biblical times - See “Demographic history of [Israel] Palestine”:
https://en.wikipedia.org/wiki/Demographic_history_of_Palestine
The Jewish People have unbroken presence in their ancestral homeland of Israel since Biblical times and previous sovereign states there, for example the Jewish Hasmonean Kingdom of Judea (see above).
By comparison:
The “Palestinians” may come from those who later invaded and occupied the Jewish land of Judea / Israel, but it is also unclear at what point the Palestinian Arabs arrived there, since they were opposed to being called a “People” until the 1960’s.

Palestinian propaganda seeks without any evidence, to falsely-assert the Palestinians come from peoples pre-dating the Jewish People, yet appearing somewhat “confused” about their ancestry, as they fail to come-up with any one convincing story. Pro-Palestinians often falsely-claim without evidence that the Palestinians are the so-called “real-Jews”, while inconsistent with the latter false-claim the Palestinians claim to their own people, likewise without evidence, that they come from the Canaanites.
The reader may also consider how there could be propaganda that the Palestinians have allegedly any sincere emotional-attachment to the Jewish ancestral homeland of Israel, when:
The Palestinians attempted to take over Jordan by force in 1970 to 1971:

And:
The Palestinians attempted to take over Lebanon by force
and were likely the cause of its civil war, in 1975 - See pages 36 to 37 (PDF pages 40 to 41) of "Development of Palestinian Militancy_Role in Lebanese Civil War by Christine E_Ganley" (copy saved to):

I hope this helps.
