That land has been Israeli for thousands of years. It has always been the Jewish homeland
and was formally recognized as such by the US and UN in the 1940s-50s thanks to President Truman.
The Palestinian Authority has made offers which would recognise Israel and its borders in peace negotiations, as Israel has made offers to Palestine too. There is even the outstanding Arab Peace Initiative which Israel has not accepted, but which has been endorsed by the Arab league and states the "Arab states will do the following: (a) Consider the Arab–Israeli conflict over, sign a peace agreement with Israel, and achieve peace for all states in the region; (b) Establish normal relations with Israel within the framework of this comprehensive peace". Unfortunately so far the various sides have still not reconciled the difference in their positions.But the land they gained was never respected by any of the surrounding countries, including Palestine.
This is a very dangerous and obviously incorrect statement. There is no single "Palestine". There are the Palestinian people, the Occupied Palestinian Territories as a geographic location and various bodies which in different ways claim to represent aspects of the Palestinian people (Such as the Palestinian Authority, Fatah and Hamas). There is however no singular ruling government in the same way you would have in a nation-state. Part of this whole struggle is Palestinian wanting to be able to do that.Palestine will stop at nothing to completely get rid of a Jewish state, no matter how legal it is
Israel has been constantly battered by Egypt and other middle eastern nations,
the way they have defended themselves successfully every time shows their resilience and why they deserve that land.
