May be each will stir shit for the other but never a full fledged war....it's a logistical nightmare even to despatch troops in large scale across Tibet...that is the only land route avilable ..Tibet is a barren inhospitable terrain ,any movement will be exposed to air attacks ...it's almost like Napolean or Hitler moving against Russians ...even if a battle is won by either side, they will eventually have to withdraw
all the current tension between china and India along the border is to gain superiority from their present post..that's about it
