The problem is that we don't have a time machine like Doctor Who. We can't go back in time and fix past mistakes, we can only deal with the reality as it is today.

Israelis Were Warned on Illegality of Settlements in 1967 Memo
by Donald Macintyre in Jerusalem Israeli ministers were secretly warned just after the Six-Day War in 1967 that any policy of building settlements across occupied Palestinian territories violated international law.
A "top secret" memo by the Foreign Ministry's then legal counsel said that would "contravene the explicit provisions of the Fourth Geneva Convention". Growth of Jewish settlements over the next three decades followed.
The official advice that a policy which is now a major obstacle to a peaceful settlement of the Israeli-Palestinian conflict had no basis in international law has been highlighted by the Israeli historian, Gershom Gorenberg. His new book, The Accidental Empire: Israel and the Birth of the Settlements will generate fresh debate on the legality of the West Bank settlements in the wake of Ariel Sharon's decision to withdraw 8,500 settlers from Gaza last August.
Most of the international community has held that Jewish settlement in the territories seized in the 1967 war contravened international law, and the Geneva Conventions in particular, but this has long been publicly contested by Israel.
The highly classified internal advice was given by Theodor Meron, who left Israel a decade later and became a leading international jurist who until the end of last year was president of the International Criminal Tribunal for the former Yugoslavia.
