Here we go again. History revision. Jordan (note, not Palestine, you know, the folks you are negotiating with?) never set a foot in Israel. It moved into 'territories occupied' illegally by Israel ...and was then a legal trustee (not an occupier or illegal population transfer-er. Israel signed up to the UN in order to be recognized. When it did so it agreed with the charter. Clearly it understood acquisition of land via war were illegitimate. You can't change the rules of the game buddy. You are only correct in one respect, the 67 lines are meaningless, the 1948 borders are the true legal borders.
