Not to worry...
An Israeli 'Edict of Expulsion' (ala that of England and Spain some centuries ago) will fix that demographic before it gets out of hand...
And it will happen so fast and so thoroughly that it will be a fait accompli, by the time that the Old Lady's Debating Society (a.k.a. the U.N.) can ineffectively piss and moan...
A few years of lightweight sanctions afterwards, negated behind-the-scenes by the US, and all will be forgiven, with ex-Palestinians building comfortable and prosperous and much safer and happier lives in Jordan and Lebanon and the like, and with the Jews finally reconquering all of Eretz Yisrael according to the 1922 Partition Proposal Map, which is all they've ever really wanted for a 'National Home for the Jews'...
'This year, in Jerusalem...'
Ending this decades-old mess the only logical and inevitable way that it was always going to end, anyway...
While a new phase of ethnic cleansing would indeed appear to be a solution, Israel would be completely cut off from trade with Europe and would become isolated via UN sanctions, which the U.S. could not veto without harming its own interests.
You have been reading the usual propaganda, there is no such map. In fact, the British were very clear that there was not be a Jewish state and confirmed itin writing to the Palestine Delegation in London at the beginning of the Mandate, source documents are a ***** for propagandists.
"These apprehensions, so far as the Arabs are concerned, are partly based upon exaggerated interpretations of the meaning of the Declaration favouring the establishment of a Jewish National Home in Palestine, made on behalf of His Majesty's Government on 2nd November, 1917. Unauthorised 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 Delegation, 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 the meeting of the Zionist Congress, the supreme governing body of the Zionist Organisation, 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 the peoples an undisturbed national development." - See more at:
