If need be, wouldn't you gladly go to the Mid East to force Israel to give Palestine the lands that's theirs?

No, because it would not end the feud. The Palestinians claim the entire area as their "historic" home and wouldn't stop at a small taste. Want to know a secret? The Al Aqsa Mosque is built on top of the ruins of a very historic place called the Temple of Jerusalem. That sort of puts the Jews as the "historic" occupants of the area, doesn't it?
