The speaker is Dr James Vaughan, of the Department of International Relations at the University of Aberystwyth in Wales, the first and arguably still the best such department in the world, which had as its inaugural head Professor Alfred Zimmern, who was of Jewish extraction.
Dr Vaughan is the author of Unconquerable Minds. The Failure of American and British Propaganda in the Arab Middle East, 1945-1957 (Palgrave, 2005), and while he continues to publish on British propaganda policy towards the Arab Middle East and Iran he is currently researching the changing attitudes and policies of Britain's main political parties towards Zionism, Israel, Palestinian nationalism and the Arab-Israel dispute.
The talk is entitled '"From Aberystwyth to San Remo" - The Birth of International Politics and the Jewish National Home' To quote the page of the original uploader, UK Lawyers for Israel Charitable Trust, it explains how scholars such as Zimmern and Sir Charles Webster
"combined idealistic internationalism and a ‘Wilsonian’ belief in the rights of small nations to self-determination with an ability to bridge the worlds of academia and politics, both through their connections to Chaim Weizmann and the Zionist Organization, and in their role as participants in the making of the post-war settlement."
