You should make yourself more familiar with the history of the War of Independence. It is not true that the UN prevented Israel from conquering the West Bank and Gaza. It may be said the UN wouldn't have been very happy had Israel taken control of those areas, but the true is the opposition came from Ben Gurion himself, who hold that ruling over areas so densely populated with hostile Palestinian Arabs, was contrary to Israel's interest. You obviously never heard of the secret accord concluded in 1947, after the Partition plan, between Golda Meir sent by her boss, and Abdullah of Transjordan, to the effect that the Jordanian would limit himself, in the coming war, to the conquest of only that part of the West Bank which had been allocated to the Palestinian state-to-be. An effect he paid later with his life. BG did conquered Gaza in 1956 to cross Sinai and reach the Canal, but made no fuss at all to disengage from it afterward, to the request of Washington and Moscow. I know that a 20 centuries old habit of complaining all the world is again us, is a habit hard to get rid of. But you should try to. It is difficult in the beginning, but after that, it comes quite easily, you will see. I know, for having been through that myself. And survived. After 58 years, the time has come to realize Israel is not just another Jewish community, but an independent state, responsible for its policy.
