Nope. Nope. There was no Palestinian nation. There is no unique Palestinian language, culture, or history. Palestinian identity was invented in the 1960s.
Wait a minute. Yes it was a vassell of the Ottoman Empire, it doesn't mean the people living ther shouldn't have had rights of autonomy. Where do you think the Palestinians originally lived prior to the Balfour Declaration? Wiki tells me the following of the areas now known as Israel and Palestine: In 1882 the population numbered approximately 320,000 people, 25,000 of whom were Jewish. In the early 1800s there was a Palestinian uprising throughout the region in response to Ottoman conscription. And at the end of WW1 Palestinian Christians and the first Palestinian nationalist organisations appeared.
From Wiki:
The Palestinian Arabs felt ignored by the terms of the Mandate. Though at the beginning of the Mandate they constituted a 90 percent majority of the population, the text only referred to them as "non-Jewish communities" that, though having civil and religious rights, were not given any national or political rights. As far as the League of Nations and the British were concerned the Palestinian Arabs were not a distinct people. In contrast the text included six articles (
2, 4, 6, 7, 11 and 22) with obligations for the mandatory power to foster and support a "national home" for the Jewish people. Moreover, a representative body of the Jewish people, the
Jewish Agency, was recognised.
[11]
The Palestinian Arab leadership repeatedly pressed the British to grant them national and political rights like representative government, reminding the British of president Wilson's
Fourteen Points, the
Covenant of the League of Nations and British promises during World War I. The British however made acceptance of the terms of the Mandate a precondition for any change in the constitutional position of the Palestinian Arabs. For the Palestinian Arabs this was unacceptable, as they felt that this would be "self murder".
[12] During the whole interwar period the British, appealing to the terms of the Mandate, which they had designed themselves, rejected the principle of majority rule or any other measure that would give a Palestinian Arab majority control over the government of Palestine
