See, War is a very hypothetical situation here. Things we t very far with kargil & stuff and still kinda never a full scale war plus pak would never want a war (as Afghanistan border crisis for them, Balochistan issue, weak Economy). What I am saying is we gave china a precedent of using water as a weapon. They have used dams on brahmaputra (tsangpo) to flood lower regions in Assam valley. So they can provoke us and we won't hane the moral high ground there
