The sharing of rivers should be purely based on scientific method. Do you know that karnataka has more arid region after rajasthan. Which fool told that TN went and teached all these technics. I don't have the history details other wise I would have argued towards it
Regarding the electricity - Do you know that Karanataka is the first so start electricity in the country. I don't think we are entirely depenedent on your state for electricity which is a aritifical way of producing electricity (Not hydro) which can be setup any where.
Karnataka lighted the entire nation by being the first in producing the electricity.
