Israel: Created to be Destroyed?

The map below shows how the U.N. first partitioned the British mandate of Palestine in 1947. Looking at this map leaves one to wonder how Israel was expected to protect itself from hostile Arabs who had rejected the partition plan out of hand. The partition plan seems almost to have been created in order to assure the destruction of the then nascent state of Israel (As almost happened during the 1948 Arab-Israeli war). It should be noted that Israel has occupied almost all of the yellow, Arab-state areas, with most of the occupation coming as a result of Israel's victory in the 1967 Six-Day war.
