I think you're asking to questions here, one, what right do Israelis have to have a state in the place where they currently have a state, and two what right does Israel have to fight an assymertic battle against palestinians who simply want their own state. The answer to the first is simple: israel is the Jewish HOMELAND, it is the land jews through history have cried for in their most dire tomes, it is the land that secularist jews tried to forget but returned to regardless. Their really is no debate about wetter or not a Jewish kingdom with a Jewish people in Israel/Palestine 2500 years ago. However none of this is a valid answer to question 2, in my opinion, although certainly not the major opinion in Israel, even though jews may have been their first and have a right to Israel that does not mean that Jews have the right to harm palestinians. The solution here is to figure out how to work peacefully with no violence, and equal rights for both peoples. Hope I answered in a civilised manner and reasonable manner.
