Answer the following question: Information: - The Burma Campaign in the South-East Asian theatre of World War II was fought in the British colony of Burma primarily between the forces of the British Empire and China, with support from the United States, against the invading forces of the Empire of Japan, Thailand, and the Indian National Army. British Empire forces peaked at around 1,000,000 land, naval and air forces, and were drawn primarily from British India, with British Army forces (equivalent to 8 regular infantry divisions and 6 tank regiments), 100,000 East and West African colonial troops, and smaller numbers of land and air forces from several other Dominions and Colonies. The Burmese Independence Army (known to the legitimate Burmese government and the Allies as the "Burmese Traitor Army" - BTA) was trained by the Japanese and spearheaded the initial attacks against British Empire forces. - The was the historical Japanese nation-state and great power that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan. - The Indian National Army (INA; "Azad Hind Fauj"); ("Lit": Free-Indian Army) was an armed force formed by Indian nationalists in 1942 in Southeast Asia during World War II. Its aim was to secure Indian independence from British rule. It formed an alliance with Imperial Japan in the latter's campaign in the Southeast Asian theatre of WWII. The army was first formed in 1942 under Mohan Singh, by Indian PoWs of the British-Indian Army captured by Japan in the Malayan campaign and at Singapore. This first INA collapsed and was disbanded in December that year after differences between the INA leadership and the Japanese military over its role in Japan's war in Asia. It was revived under the leadership of Subhas Chandra Bose after his arrival in Southeast Asia in 1943. The army was declared to be the army of Bose's "Arzi Hukumat-e-Azad Hind" (the Provisional Government of Free India). Under Bose's leadership, the INA drew ex-prisoners and thousands of civilian volunteers from the Indian expatriate population in Malaya (present-day Malaysia) and Burma. This second INA fought along with the Imperial Japanese Army against the British and Commonwealth forces in the campaigns in Burma, in Imphal and at Kohima, and later against the successful Burma Campaign of the Allies. - The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states.

As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories. - The South-East Asian Theatre of World War II was the name given to the campaigns of the Pacific War in Burma, Ceylon, India, Thailand, Indochina, Malaya and Singapore. Objectives for conquering these countries included the seizure of natural resources such as rubber and petroleum from European colonies in the region.
