This video is from a 1988 documentary on Rabbi Meir Kahane and the Kach movement. Two years after this, Kahane was assassinated by an Egyptian jihadi in New York, and his party was labeled as a terrorist group. See for yourself what made Kahane a person to be feared.
Thanks to Shlomo Wollins at Wejew.com who found this in parts, put it together and improved the quality of the video.
