Documentary filmmaker Levi Zini had a eureka moment: The reason Prime Minister Ariel Sharon conceived of and implemented Israel’s so-called disengagement from the Gaza Strip in 2005 was to demarcate Israel’s final borders. In Zini’s perception, the evacuation of the Gaza settlements was part of Sharon’s grand plan to liberate Israel from the deceptive interim situation created by the 1967 Six-Day War. No longer would Judea & Samaria and Gaza be “administered territories,” while the Green Line that ostensibly separates them from Israel proper became ever more blurred. Henceforth, Israel would be a state with boundaries clearly defined by the separation barrier to the east and the line marking the Gaza withdrawal to the south. This is Zini’s surprising thesis, as presented in the three-part mini-series “Sharon: the Leadership Years,” which aired recently on the Kan public broadcasting channel.
