The Allon Plan was the unoffical Israeli
policy developed after the Six Day War
concerning Jewish settlements in the newly conquered territories on the West Bank
of the Jordan River
. Named after it's champion Labor Minister (and later Foreign Minister) Yigal Allon
Allon felt the settlements were necessary to protect Jerusalem. He thought that with Jewish settlement, the Palestinians could be better contained, while diplomats worked on setting up a semi-automous state for the Palestinians in the area. This unofficial policy would continue until the Rabin-Arafat peace talks in 1993.
