Question: Who was the first Prime Minister of the country that had been compared to Gibraltar?

full_context: Document 1: History of Australia: British Malaya quickly collapsed, shocking the Australian nation. British, Indian and Australian troops made a disorganised last stand at Singapore, before surrendering on 15 February 1942. Around 15,000 Australian soldiers became prisoners of war. Curtin predicted that the "battle for Australia" would now follow. On 19 February, Darwin suffered a devastating air raid, the first time the Australian mainland had ever been attacked by enemy forces. Over the following 19 months, Australia was attacked from the air almost 100 times.
Document 2: British Empire: By the start of the 20th century, Germany and the United States challenged Britain's economic lead. Subsequent military and economic tensions between Britain and Germany were major causes of the First World War, during which Britain relied heavily upon its empire. The conflict placed enormous strain on the military, financial and manpower resources of Britain. Although the British Empire achieved its largest territorial extent immediately after World War I, Britain was no longer the world's pre-eminent industrial or military power. In the Second World War, Britain's colonies in South-East Asia were occupied by Imperial Japan. Despite the final victory of Britain and its allies, the damage to British prestige helped to accelerate the decline of the empire. India, Britain's most valuable and populous possession, achieved independence as part of a larger decolonisation movement in which Britain granted independence to most territories of the Empire. The transfer of Hong Kong to China in 1997 marked for many the end of the British Empire. Fourteen overseas territories remain under British sovereignty. After independence, many former British colonies joined the Commonwealth of Nations, a free association of independent states. The United Kingdom is now one of 16 Commonwealth nations, a grouping known informally as the Commonwealth realms, that share one monarch—Queen Elizabeth II.
Document 3: Consequences of the attack on Pearl Harbor: On December 8, 1941, Japan declared war on the United States and the British Empire. The Japanese document discussed world peace and the disruptive actions of the United States and the United Kingdom. The document claimed all avenues for averting war had been exhausted by the Government of Japan.
Document 4: Leader of the Opposition (Singapore): The Leader of the Opposition of Singapore is usually the leader of the second largest political party represented in the Parliament of Singapore. During the 1955 Legislative Assembly election, the late Lee Kuan Yew was the "de facto" Leader of the Opposition, as the People's Action Party was then the second largest political party represented in the Legislative Assembly.

Document 6: Goh Chok Tong: Goh Chok Tong (born 20 May 1941; Chinese: 吴作栋; Pe̍h-ōe-jī: Gô͘ Chok-tòng) is a Singaporean politician. A member of the People's Action Party (PAP), he became Singapore's second Prime Minister on 28 November 1990, succeeding Lee Kuan Yew, and served in the role until 12 August 2004, when he stepped down and was succeeded by Lee Hsien Loong. He subsequently served as Senior Minister until May 2011, and as Chairman of the Monetary Authority of Singapore (MAS). He continues to serve as a Member of Parliament (MP) representing the Marine Parade Group Representation Constituency and holds the honorary title of "Emeritus Senior Minister".

Document 7: Pacific War: In January, Japan invaded Burma, the Dutch East Indies, New Guinea, the Solomon Islands and captured Manila, Kuala Lumpur and Rabaul. After being driven out of Malaya, Allied forces in Singapore attempted to resist the Japanese during the Battle of Singapore but surrendered to the Japanese on 15 February 1942; about 130,000 Indian, British, Australian and Dutch personnel became prisoners of war. The pace of conquest was rapid: Bali and Timor also fell in February. The rapid collapse of Allied resistance had left the "ABDA area" split in two. Wavell resigned from ABDACOM on 25 February, handing control of the ABDA Area to local commanders and returning to the post of Commander-in-Chief, India.

Document 9: British Empire: In December 1941, Japan launched, in quick succession, attacks on British Malaya, the United States naval base at Pearl Harbor, and Hong Kong. Churchill's reaction to the entry of the United States into the war was that Britain was now assured of victory and the future of the empire was safe, but the manner in which British forces were rapidly defeated in the Far East irreversibly harmed Britain's standing and prestige as an imperial power. Most damaging of all was the fall of Singapore, which had previously been hailed as an impregnable fortress and the eastern equivalent of Gibraltar. The realisation that Britain could not defend its entire empire pushed Australia and New Zealand, which now appeared threatened by Japanese forces, into closer ties with the United States. This resulted in the 1951 ANZUS Pact between Australia, New Zealand and the United States of America.
Document 10: The Istana: The Istana is the official residence and office of the President of Singapore. Meaning "palace" in Malay, it is where the President receives and entertains state guests. The Istana is also the working office of the Prime Minister of Singapore.
Document 11: British Empire: By the turn of the 20th century, fears had begun to grow in Britain that it would no longer be able to defend the metropole and the entirety of the empire while at the same time maintaining the policy of "splendid isolation". Germany was rapidly rising as a military and industrial power and was now seen as the most likely opponent in any future war. Recognising that it was overstretched in the Pacific and threatened at home by the Imperial German Navy, Britain formed an alliance with Japan in 1902 and with its old enemies France and Russia in 1904 and 1907, respectively.

Document 14: Modern history: On December 7, 1941, Japan attacked the United States at Pearl Harbor, bringing it too into the war on the Allied side. China also joined the Allies, as eventually did most of the rest of the world. China was in turmoil at the time, and attacked Japanese armies through guerilla-type warfare. By the beginning of 1942, the major combatants were aligned as follows: the British Commonwealth, the United States, and the Soviet Union were fighting Germany and Italy; and the British Commonwealth, China, and the United States were fighting Japan. The United Kingdom, the United States, the Soviet Union and China were referred as a "trusteeship of the powerful" during the World War II  and were recognized as the Allied "Big Four" in Declaration by United Nations These four countries were considered as the "Four Policemen" or "Four Sheriffs" of the Allies power and primary victors of World War II. From then through August 1945, battles raged across all of Europe, in the North Atlantic Ocean, across North Africa, throughout Southeast Asia, throughout China, across the Pacific Ocean and in the air over Japan.
Document 15: British Empire: The changing world order that the war had brought about, in particular the growth of the United States and Japan as naval powers, and the rise of independence movements in India and Ireland, caused a major reassessment of British imperial policy. Forced to choose between alignment with the United States or Japan, Britain opted not to renew its Japanese alliance and instead signed the 1922 Washington Naval Treaty, where Britain accepted naval parity with the United States. This decision was the source of much debate in Britain during the 1930s as militaristic governments took hold in Japan and Germany helped in part by the Great Depression, for it was feared that the empire could not survive a simultaneous attack by both nations. Although the issue of the empire's security was a serious concern in Britain, at the same time the empire was vital to the British economy.
