I fail to understand why India would bother merging Nepal into its border given there are so many problems festering everyday in the latter. This is just the disillusion lot of Nepalis harbor. Reality check: Brits chose not to invade Nepal because they could exercise their hegemony through their Rana puppets. If you can enjoy all the benefits without lifting a finger, why take burden onto yourself with all the negatives, eh? Same goes with India. With Nepal as sovereign, but under-influence, nation, India has much to gain and very little to loose. Think about it. With Nepal, India has a perfect fence against China, their significant adversary. Furthermore, Nepal has been under India's beck and call ever since Tribhuvan sought refuge within Nehru's coat. So, if India can do whatever it wants in Nepal anyway, why take additional responsibilities, risks and all the problems therein by making Nepal its another state? After all, why buy the cow if you can have all the milk for free? So don't worry. India does not want to invade Nepal. In a sense, that is already done, whether you know it or not, like it or not.
