There is an excellent contemporary article by the Jewish writer Hannah Arendt that I would recommend.

And even if the Jews were to win the war, its end would find the unique possibilities and the unique achievements of Zionism in Palestine destroyed. The land that would come into being would be something quite other than the dream of world Jewry, Zionist and non-Zionist. The “victorious” Jews would live surrounded by an entirely hostile Arab population, secluded inside ever-threatened borders, absorbed with physical self-defense to a degree that would submerge all other interests and activities. The growth of a Jewish culture would cease to be the concern of the whole people; social experiments would have to be discarded as impractical luxuries; political thought would center around military strategy; economic development would be determined exclusively by the needs of war. And all this would be the fate of a nation that—no matter how many immigrants it could still absorb and how far it extended its boundaries (the whole of Palestine and Transjordan is the insane Revisionist demand)—would still remain a very small people greatly outnumbered by hostile neighbors.

Under such circumstances (as Ernst Simon has pointed out) the Palestinian Jews would degenerate into one of those small warrior tribes about whose possibilities and importance history has amply informed us since the days of Sparta. Their relations with world Jewry would become problematical, since their defense interests might clash at any moment with those of other countries where large numbers of Jews lived. Palestine Jewry would eventually separate itself from the larger body of world Jewry and in its isolation develop into an entirely new people. Thus it becomes plain that at this moment and under present circumstances a Jewish state can only be erected at the price of the Jewish homeland.

Of course, I must also emphasize that millions of Israelis have no further sin than being born in Israel, and that though the establishment of Israel was a mistake, Israel also has a right to exist in the modern day under the same terms as any other country.
