If Oceania were to conquer the areas that used once to be known as France and Germany, it would be necessary either to exterminate the inhabitants, a task of great physical difficulty, or to assimilate a population of about a hundred million people, who, so far as technical development goes, are roughly on the Oceanic level.
Maybe that's the case with Pakistan. They're socially or ideologically so inferior that having them back with India will harm indian society more than it'll prove good.
