The campaign was also strongly affected from the political atmosphere which erupted in the South-East Asian regions occupied by Japan, who pursued the Pan-Asianist policy of a Greater East Asia Co-Prosperity Sphere. These led to a Japanese-sponsored revolution during the initial invasion and the establishment of the State of Burma, in which the Provisional Government of Free India, with its Indian National Army, was headquartered. The dominating attitude of the Japanese militarist who commanded the army stationed in the country, which ultimately doomed the co-prosperity sphere as a whole, led to local hopes for real Independence fade and the war-time established Burma National Army revolted in 1945. On the Allied side political relations were mixed for much of the war. The China Burma India Theater American-trained Chinese X Force led to cooperation between the two countries, but the clashing strategies proposed by Vinegar Joe Stilwell and Chinese Generalissimo Chiang Kai-shek would lead to Stilwell's eventual firing from his position as American Commander of the theater. On the other hand, China-India relations were positive from the cooperative Burma Road, built to reach the Chinese Y Force and the Chinese war effort inside of China, as well as from the heroic missions over the extremely dangerous air route over the Himalayas, nicknamed The Hump. The campaign would have a great impact on the independence struggle of Burma and India in the post-war years.
