Indeed.  Millennia of migrations, inter-marriage and conversions make contemporary Jews related to ancient Hebrews as much as today's Roman Catholics are to ancient Romans. Even if they were, this would still not justify Zionism and its ongoing colonization of Palestine: my "ancestral homeland" 3000 years ago may well be Israel, Peru or Timbuctou, but that does not give me the right to displace or dominate those who lived there for generations (if not centuries) and have no other home.
