As someone who has no conflict of interest AND who is very familiar w the topic (watched every israel/Palestine doc I know of; from highly partisan borderline propaganda docs on both POVS to every PBS frontline on the issue to docuseries from the 50s and 60s) this is the most balanced documentary I've seen by far. Contributors are all impressive ppl and both sober/thoughtful in their commentary. Also, as the history of zionism/Jewish immigration to Palestine is chronologically told from both POV relevant impartial context accompanies each major event/conflict. Context extremely important to understanding decisions made (and how simultaneously occurring global events/attitudes influenced those decisions)
EXAMPLE
1948 War and David Ben Gurions decision not to let Palestinians back to their homes who fled country.
At first glance from today's perspective that seems extremely harsh and inhumane. But, when the context is added that it's only a couple years after World War II and in Europe at the same time millions of people are forcibly migrated into the new post World War II nation state borders. For example, Germans who previously lived in Poland on the Danzig corridor or in Czechoslovakia in the sudetenland all we're forced to migrate into Germany. And non-germans no longer feel comfortable being minorities in other Nations.
It doesn't justify or rationalize not letting 700,000 people back to their homes after a war that last few weeks but it does give very necessary concurrently occurring Global events that give some substantiation as to why such a seemingly harsh policy was enacted. Because it was occurring at the same time in Europe with other ethnicities and because of the enormous trauma the Jewish population just endured and their understandable reaction to want to only be around other Jews.
