Zionist leaders stressed that their goals were peaceful and no threat to Palestinian Arabs.
However....

In 1940 Joseph Weitz, an official of the Yishuv, responsible for Jewish colonization, noted in his diary:

"Between Ourselves it must be clear that there is no room for both peoples together in this country.... We shall not achieve our goal of being an independent people with the Arabs in this small Country. The only solution is a Palestine, at least Western Palestine (west of the Jordan river without Arabs. And there is no other way than to transfer the Arabs from here to the neighbouring countries, to transfer all of them; not one village, not one tribe, should be left."

I do however agree with Amos that, to quote Ali Abunimah, an American Journalist

'We should be under no illusion that seeking a one-state solution is a short-cut to peace. On the contrary, we need to prepare for years of sustained political struggle.

But at least this path offers an alternative to violence combined with the prospect that real peace can be achieved. Persisting along the present path offers hope of neither.....

Israeli and Palestinian supporters of a one-state solution must build a new movement. This partnership must work to translate the vast international sympathy for the Palestinian cause into active support for the transformation -- with international assistance and guarantees -- of Israel and the Occupied Territories into a democracy for all its inhabitants

The burden to persuade Israelis lies largely with Palestinians, who while demanding equal rights and an end to the Jewish Israeli monopoly on power, must hold out a future in which the two communities express their identities as equals rooted by right and history in the same land.....

even in the darkest days of apartheid, the African National Congress under Nelson Mandela offered white South Africans a future of reconciliation, not revenge. As in South Africa, a truth and reconciliation process can help both peoples overcome the pain of the past even as they build a just future together'
