The use of of words such as lebenstraum [sic] and other Nazi era terminology and allusions in the context of Israel by the usual Jew haters is indeed offensive, it is also a libel and marks the users for what they are.

Teribus is 100% correct in stating that there is no such thing as the 1967 borders, what there is is the so called "Green line" which is the demarcation line set out in the 1949 Armistice Agreements between Israel and its neighbors (Egypt, Jordan, Lebanon and Syria) after the 1948 Arab–Israeli War. It is also used to mark the line between Israel and the territories captured in the Six-Day War, including the West Bank, Gaza Strip, Golan Heights and Sinai Peninsula.

The original armistice agreements were clear (at Arab insistence) that they were not creating permanent borders. The Egyptian-Israeli agreement stated "The Armistice Demarcation Line is not to be construed in any sense as a political or territorial boundary, and is delineated without prejudice to rights, claims and positions of either Party to the Armistice as regards ultimate settlement of the Palestine question." From Wiki.

The territorial boundary or border will be determined by negotiation when the Palestinians accept a two state solution.
