The International Legal Chain Establishing Israel's Legitimacy
Israel's legitimacy rests on an unbroken chain of international law — from the 1917 Balfour Declaration through League of Nations treaties, the San Remo Conference, and finally the United Nations Charter.
The Balfour Declaration (1917)
On November 2, 1917, British Foreign Secretary Arthur James Balfour confirmed Britain's support for "the establishment in Palestine of a national home for the Jewish people." This declaration was later incorporated into binding international law.
The San Remo Conference (1920)
At the San Remo Conference of April 1920, the Principal Allied Powers formally adopted the Balfour Declaration as binding international policy and resolved to assign the Mandate for Palestine to Great Britain with the explicit purpose of implementing the Jewish national home.
The League of Nations Mandate (1922)
The League of Nations formally approved the British Mandate for Palestine on July 22, 1922. The Mandate's Preamble explicitly recognized "the historical connection of the Jewish people with Palestine" and required facilitation of Jewish immigration and settlement.
UN Charter Article 80
When the United Nations replaced the League of Nations in 1945, Article 80 of the UN Charter preserved all existing rights under League mandates — including Jewish national rights in Palestine. Known as "the Palestine article," it bound the UN to honor commitments made to Jewish self-determination.
UN Resolution 181 (1947)
On November 29, 1947, the UN General Assembly passed Resolution 181 recommending partition into Jewish and Arab states. The Jewish leadership accepted; Arab states rejected it and launched a military invasion. Resolution 181 constitutes explicit UN recognition that a Jewish state was legitimate under international law.
Israel's Declaration of Independence (1948)
On May 14, 1948, citing natural and historic right and UN Resolution 181, Israel declared independence. The United States recognized the new state within hours. Today Israel is recognized by over 160 countries and is a full UN member with peace treaties with six Arab states.
Conclusion
The legal case for Israel's existence is among the strongest of any modern state: an unbroken chain of international instruments from 1917 through 1948, reaffirmed by UN membership and bilateral treaties.
