The following link shows Isreals borders past and present and how they have expanded since 1948.
It also shows maps of biblical Isreal.Can we see the future ambitions of Isreal in these ancient maps?These maps are provided by The Isreali Gov.

so, when exactly did israel cease to exist between 100BC and 1920AD? seems to me that there's some 2000 years where isreal did not exist. does this not suggest that the palestinians have a legitimate claim to that land?
