It’s hard to imagine today, but for a tense few hours in 1973, it looked like the country of Israel might cease to exist. Half a century later, Israeli-American filmmaker Guy Nattiv has made a new film about Israel's prime minister at the time, Golda Meir, and those fateful few days during the Yom Kippur War. He speaks with GZERO World's Alex Kliment about why he wanted to reframe the former PM's story, who is played by Helen Mirren.
