Here is the British position on Palestine explaining the meaning of the Balfour Declaration.
{...
British White Paper of June 1922
The Secretary of State for the Colonies has given renewed consideration to the existing political situation in Palestine, with a very earnest desire to arrive at a settlement of the outstanding questions which have given rise to uncertainty and unrest among certain sections of the population. After consultation with the High Commissioner for Palestine [Sir Herbert Samuel] the following statement has been drawn up. It summarizes the essential parts of the correspondence that has already taken place between the Secretary of State and a delegation from the Moslem Christian Society of Palestine, which has been for some time in England, and it states the further conclusions which have since been reached.
The tension which has prevailed from time to time in Palestine is mainly due to apprehensions, which are entertained both by sections of the Arab and by sections of the Jewish population. These apprehensions, so far as the Arabs are concerned are partly based upon exaggerated interpretations of the meaning of the
[Balfour] Declaration favouring the establishment of a Jewish National Home in Palestine, made on behalf of His Majesty's Government on 2nd November, 1917.
Unauthorized statements have been made to the effect that the purpose in view is to create a wholly Jewish Palestine. Phrases have been used such as that Palestine is to become "as Jewish as England is English." His Majesty's Government regard any such expectation as impracticable and have no such aim in view. Nor have they at any time contemplated, as appears to be feared by the Arab deegation, the disappearance or the subordination of the Arabic population, language, or culture in Palestine. They would draw attention to the fact that the terms of the Declaration referred to do not contemplate that Palestine as a whole should be converted into a Jewish National Home, but that such a Home should be founded `in Palestine.' In this connection it has been observed with satisfaction that at a meeting of the Zionist Congress, the supreme governing body of the Zionist Organization, held at Carlsbad in September, 1921, a resolution was passed expressing as the official statement of Zionist aims "the determination of the Jewish people to live with the Arab people on terms of unity and mutual respect, and together with them to make the common home into a flourishing community, the upbuilding of which may assure to each of its peoples an undisturbed national development."
It is also necessary to point out that the Zionist Commission in Palestine, now termed the Palestine Zionist Executive, has not desired to possess, and does not possess, any share in the general administration of the country. Nor does the special position assigned to the Zionist Organization in Article IV of the Draft Mandate for Palestine imply any such functions. That special position relates to the measures to be taken in Palestine affecting the Jewish population, and contemplates that the organization may assist in the general development of the country, but does not entitle it to share in any degree in its government.
Further, it is contemplated that the status of all citizens of Palestine in the eyes of the law shall be Palestinian, and it has never been intended that they, or any section of them, should possess any other juridical status. So far as the Jewish population of Palestine are concerned it appears that some among them are apprehensive that His Majesty's Government may depart from the policy embodied in the
Declaration of 1917. It is necessary, therefore, once more to affirm that these fears are unfounded, and that that Declaration, re affirmed by the Conference of the Principle Allied Powers at San Remo and again in the Treaty of Sevres, is not susceptible of change.

So clearly Zionist had lied that they did not want any part in the government, in order to emigrate, and they illegal started a terrorist campaign in order to get the British to leave, so they could murder and take over by force.
