A secret legal memo: Did Israel's leadership know its settlements were illegal?

In short: In 1967, a top-secret memorandum revealed that the Israeli government was aware of the international law implications regarding new civilian settlements. While the state later navigated complex legal loopholes to establish these communities, the original legal counsel’s warning remains a pivotal point of historical and legal debate.

Following the 1967 Six-Day War, Israel occupied the West Bank, Gaza Strip, Sinai Peninsula, East Jerusalem, and Golan Heights. During this period, Theodor Meron—the government's primary authority on international law—provided a confidential memorandum to Foreign Minister Abba Eban. Meron explicitly stated that while short-term military outposts might be permissible, establishing civilian settlements in these areas would directly violate the Fourth Geneva Convention. He characterized the prohibition on such population transfers as categorical.

Despite this internal legal guidance, Israel proceeded with settlement construction. In September 1967, Kfar Etzion became the first civilian settlement in the West Bank. Throughout the 1970s, the Israeli Supreme Court often upheld these developments by classifying them as temporary measures necessary for military security. However, after the Likud party took power in 1977, the government shifted its legal strategy, beginning to declare land in the West Bank as 'state land' rather than relying on the temporary status implied by earlier regulations.

The international community maintains a broad consensus on the illegality of these settlements. The International Court of Justice (ICJ) reaffirmed this in a 2024 advisory opinion, and numerous UN Security Council resolutions—including 446 (1979), 478 (1980), and 2334 (2016)—deem the activity a violation of international law. While Israel disputes these claims by arguing the territories are 'disputed' rather than occupied, the ICJ countered these arguments in its recent findings.

This legal friction creates a complex landscape for international relations. For instance, while the UN considers the Jerusalem Law null and void, the United States recognizes Jerusalem as Israel's capital via the Embassy Act. Similarly, while most of the world views settlements as illegal, the U.S. stated in 2019 that it no longer viewed them as inconsistent with international law. These diverging interpretations highlight how one set of facts can produce vastly different legal and political realities.
