Most of the leaders in India take Nepal as a good friend, younger brother. There are parts of RAW and other politics involved, vestigial of Nehru and Gandhi doctrine, but for the most part India and Indians are our ally. Yes, they do have our water resources in their sight, but it is upto us to make it win-win for both as naturally they will be thinking mostly in terms of what's best for them. I highly doubt they think in terms of what's worst for us.
