Given that you can't read, I'm sure you also don't know history. It was the Likud that gave Egypt the Sinai in 1979. It was a Likud government under Netanyahu that gave Hebron and parts of the West Bank to Arafat. It was a Likud-Kadima government under Sharon that gave Gaza to the Palestinian Authority.
"Second, a United Nations vote on Palestinian statehood would give Israel an opportunity to rectify the mistake we made in 1967 by failing to annex all of the West Bank (as we did the eastern half of Jerusalem). We could then extend full Israeli jurisdiction to the Jewish communities and uninhabited lands of the West Bank.....These Palestinians would not have the option to become Israeli citizens, therefore averting the threat to the Jewish and democratic status of Israel by a growing Palestinian population."
You're right that Begin gave back the Sinai but that was because the Likud, aside from a few extremists, never regarded that land as part of Greater Israel. Begin if you remember never tired of waxing eloquent about Judea and Samaria NOT the Sinai.
