Casey was an Australian politician who served as the British government’s chief adviser in the Middle East. In November 1939 he went to London as the Australian government’s representative and in the following year was sent to Washington. He made such a good impression on the British that they made him Minister of State in the Middle East at Cairo. He chaired the Middle East Defense Committee which dealt with political, economic and propaganda problems and it fell to him to announce to the US and British governments that Tobruk had fallen. After the end of the campaign in North Africa Casey became involved in the Arab-Jewish question and tried to act as a mediator between French and anti-French factions in the Lebanon. In 1944 he was made Governor of Bengal.
