> it was a creation of the second world war

The modern state of Israel with its present borders were a creation of the Second World War. But if you go back in time to ~1000 BC, Jewish people occupied the entire region (much broader than just Israel), and they are the only surviving indigenous people of the region. This isn’t even controversial. Virtually all historians and scholars acknowledge this because there is literal physical evidence in the buildings at Temple Mount and elsewhere, which are all dated back to that time.
