Stop lying. Israel prevents nobody from forming their own state; they stop them from taking Israeli land as their own state.
What I stated about the UN is fact, incidentally.
Even with the partition plan the Arabs were to have half the land. As for the West Bank and Gaza, under both International Law and Israeli Law this land is under military occupation and is not a part of Israel. If Israel wants it they should annex it. But then they would have to give citizenship to the Arab population. The local Arab population is in possession of the land. Israel needs to recognize this either as a separate nation or as citizens of a single nation. They have no right to the land without its population.

I will not argue with your characterization of the UN between 1972 and 1981 but this has no bearing on the nature of the UN in 1948 which APPROVED the recommendation for partition.
