Gershom Gorenberg has written that the Israeli government knew at the outset that it was violating the Geneva Convention by creating civilian settlements in the territories under IDF administration. He explained that as the legal counsel of the Foreign Ministry, Theodor Meron was the Israeli government's expert on international law. On 16 September 1967 Meron wrote a top secret memo to Mr. Adi Yafeh, Political Secretary of the Prime Minister regarding "Settlement in the Administered Territories" which said "My conclusion is that civilian settlement in the Administered territories contravenes the explicit provisions of the Fourth Geneva Convention." Moshe Dayan authored a secret memo in 1968 proposing massive settlement in the territories which said “Settling Israelis in administered territory, as is known, contravenes international conventions, but there is nothing essentially new about that.”
