I don't know if you understand the connotation that "revisionist" has when it comes to history... but whatever the case, it may surprise you to learn that the Jews were defeated and forced to disperse from what is now Israel about two thousand years ago. They lost the land, and just like any other losing nation is not entitled to it. Over the centuries, there were always some Jews living in the region, but it was not until the late 19th century that there was a drive to reclaim the lost homeland. That's fact, not revisionism.
