That is an oversimplified and slanted accounting of the events leading up to the establishment of the state of Israel.

"By emphasizing their acceptance of the idea of partition and Arab rejection of it, while ignoring the deep injustice written into the details of the proposal in terms of both land and population, Zionists were able to cloak the ensuing conquest and displacement of Palestinians as both legitimate and defensive. The UN Partition Plan thus represents both the fruits of Zionist efforts to secure international recognition of Jewish sovereignty in Palestine and the immediate precursor to the establishment of the State of Israel in May 1948, predicated as it was on the expulsion of hundreds of thousands of Palestinians from their lands."
