"We [the Ichud Association] describe our program as that of a bi-national state -- that is, we aim at a social structure based on the reality of two peoples living together... The road to be pursued is that of an agreement between the two nations -- naturally also taking into account the productive participation of smaller national groups -- an agreement which, in our opinion, would lead to Jewish-Arab cooperation in the revival of the Middle East, with the Jewish partner concentrated in a strong settlement in Palestine. This cooperation, though necessarily starting out from economic premises, will allow development in accordance with an all-embracing cultural perspective and on the basis of a feeling of at-oneness, tending to result in a new form of society."
