Which is unthinkable, much like people speaking American English are necessarily fans of the military industrial complex.

It's not unthinkable. Many supporters of Jewish Voice for Peace are in this category, meaning they speak hebrew and are anti-zionist. Let's not forget that JVP is the largest jewish anti-zionist organization in the world.

In relation to your example though, there is no common ground between hebrew and american english because hebrew was the mother tongue of no one for almost 2000 years.

Thank you for the info

Tantura (2022) - Internet Archive

Description: When Israeli graduate student Teddy Katz meticulously documented a massacre of Palestinian civilians surrounding Israel's independence, he was initially celebrated for his groundbreaking work. But soon, he was stripped of his degrees and was publicly shamed as a fraudulent traitor. Decades later, incendiary new evidence emerges to corroborate Teddy's initial findings, not just vindicating him, but raising profound questions about how Israelis — and we all — deal with the darker chapters of history.

IMDb: In the war of 1948 hundreds of Palestinian villages were depopulated. Israelis call it 'The War of Independence. Palestinians call it 'Nakba"'. The film examines one village - Tantura and why "Nakba" is taboo in Israeli society.

can anybody who speaks Hebrew confirm the subtitles are accurate

I doubt you'll get an answer to this, unless they speak hebrew and are anti-zionist as well. Btw for those interested in digging deeper into these testimonies are in relation to the Tantura Massacre in 1948, as mentioned in this video.
