Mr. Manjunath, Water cannot be equally shared as the extent of cultivated land in both these states vary enormously. Remember 1/3rd cauvery flows in Karnataka whereas 2/3rd of it flows in Tamilnadu. Geographically, the total area cultivated around cauvery in Tamilnadu is twice as that Karnataka. So it is awared more share. Despite of being awarded more share on basis of the extent of cultivated land, Tamilnadu is denied the allocated share by karnataka every year. Karnataka is trying to increase its agricultural land even made an artificial channel but Tamilnadu is only trying to protect the already cultivated.
Dont mix up things like Rajiv Gandhi assasination, Srilankan violence with this issue. If you want, I can argue with you regarding these issues seperately. These issues are totally different and be specific. Its Karnataka that is acting as big brother and twisting its arms every time an issue crops up by attacking innocent people and spew venom.
