India taking over nepal is impossible thing to imagine. In todays world it is just not possible. Being a nuclear power it will be very bad PR for india to do such things... Indian economy depends very much on america, europe, china etc... it can not do such things if it looks after its interests... further there are people in india who want to have nepal as 'hindu' rastra... these people (mad as they are) will never accept merging of a hindu country with a 'secular' country like india. But india might try to take 'advantage' of the situation. For instance 'defence' related treaties might be pushed. After all present situation is surely favorable for indian establishment to try such things.... More involvement of other members of international community in solution process will remove this possibility as well... Also recently india reject royal governments proposal about karnali project.. instead waiting for a democratic government so that such treaty can be made legally in full accordance with international law... To sum up. India may try to seek its benifits while helping nepalese people. But incase it really acts as a real friend in this moment then I am sure India will get much more security from nepal side because of public goodwill than any treaty can get it.
