“This article is based on a letter written by filmmaker Hugh Kitson, producer of “Whose Land,” retired British Army officer Col. Richard Kemp CBE and the Marquess of Reading to Crispin Blunt, MP, in response to a letter sent to the British prime minister and foreign secretary on 1st May 2020 by members of the House of Commons and the House of Lords claiming that Israel extending its sovereignty to the West Bank would constitute a violation of international law.”
The British government should be supporting the Trump peace process, rather than punishing Israel for exercising a right that was granted to it under international law 100 years ago.
The legal right of the Jewish people to reconstitute their historic homeland was recognized at the San Remo Conference of 1920 and by virtue of the Mandate for Palestine that resulted from it. This was unanimously endorsed by all 51 nations that were in the League of Nations, which then constituted the entire international community.
International lawyer Cynthia D. Wallace writes: “The Mandate system had been set up under Article 22 of the Covenant of the newly formed League of Nations that had arisen out of the Paris peace process to deal with such post-war emerging territories. At San Remo, the Mandate for Palestine was entrusted to Great Britain as a ‘sacred trust of civilization,’ and the language of the Balfour Declaration was enshrined in both the San Remo Resolution and the League Mandate, which stand on their own as valid international legal instruments with the full force of treaty law.”
Wallace is by no means the only international lawyer who recognizes that the right of the Jewish people to reconstitute their national home in their historic homeland was enshrined in international law at San Remo. At the heart of the historic Jewish homeland was the Old City of Jerusalem and the territory today known as “the West Bank.”
Territorially the legal right of the Arabs to self-determination was accorded to them by the Mandates for Syria and Lebanon (under the French), and Mesopotamia—now Iraq—(under the British), and later in Transjordan, which was originally part of the Mandate for Palestine.
