From The Hindu Archives, we see "the official [Indian] map as on August 15, 1947." This official 1947 Indian government map does not include China's Aksai Chin.
From The Hindu Archives, we see "the [new Indian] map in 1950, with the colour wash. The maps were published under the authority of India's Surveyor General, Brigadier G.F. Heaney." This official 1950 Indian government map magically claims China's Aksai Chin.
From 1947 to 1950, India decided it would unilaterally redraw the Sino-Indian boundary map and claim Aksai Chin. I like this Indian trick. I think China should redraw its maps Indian-style and claim whatever we want of Indian territory.
The Indians are doing it and we should copy them. If the Indians are shameless, we should become just as shameless. The only way to deal with an aggressive and expansionist neighbor is to use their own dirty trick of redrawing maps (without any relation to history) against them.
