If we Evil chineses are able to build Tibet rail..it 100% more difficut than diverting water by dig a canal, your fighters and missles will just hit the low value target..we can fix in matter of hours, I bet you never heart of the great canal that China has build to join northern to souther china during sui Dinasty??..you're gamble with your luck man if you think we don't have any mean to play with that river...we can prevent a single drop of water flown to you borde if we want but we don't play with innocent civilian daily basis need..water is life and dead for them.
not only would you be diverting water from us but also for Bangladesh a friendly country besides your gov't has said they won't divert the water if they do then obviously it will get a response from us either military action or some other solution your scientists already said it was not feasible to divert the Brahmaputra's waters stop posting hypothetical situations on here like an idiot just to satisfy yourself
when our civilians are bombed and attacked by another country's terrorists we will react whatever way we want to they mess with our civilians we mess with theres end of story
and stop boasting on about yourselves your war talk and other crap does not do crap just because you got lucky in 1962 does not mean it will happen again this was already proved in 1967 when we ran you out of Sikkim the fact that you guys mobilized troops in 1965 on the border in aid of Pakistan was another event that did not happen because we posted troops and what happened? nothing same in 1971 Pakistan banked on you guys coming to there aid we sent up 8 mountain divisions to the border and what happened? nothing so now go back to sleep because we are ready and prepared this time
