How feasible are European Settler colonies established by the Colonial Empires in the sparsely populated regions of Asia? For example, British ruled India, which is a heavily populated region, in the mainland. Could they annex Afghanistan, for example and establish thriving settler colonies like in Australia, in those regions that are sparsely populated, like the Afghanistan and Western/Northwestern parts of then India and now Pakistan? Eventually, some could then be established in the Mainland Undivided India, too, without harming the areas settled already by the natives. Could this happen in an alternate scenario?
