A quick history lesson.
1937: The British government recommends partitioning Palestine into an Arab state on roughly 80 percent of the land and a Jewish state on the rest. The Zionist leadership accept this offer of a mini-state on 20 percent of the territory. The Arabs refuse.
1947: The UN votes in favour of Resolution 181 – the partition of Palestine into a Jewish state and an Arab state, this time roughly 50:50. The Jews accept, the Arabs refuse and, for good measure, declare that they will strangle the new Jewish state at birth.
