The basis of building the Indian Air Force (IAF) till about the mid eighties was mainly with the focus on our western adversary, since other nations sharing a border with India were neither hostile nor held significant martial clout in the region, all but China. For some strange reason, for a very long time, we decided not to talk about the ‘Red threat’ and ‘war gaming’ in India which was limited to to Pakistan. Despite having fought a war and numerous border skirmishes, it is only during recent times did the military strategy of India start a new chapter, protagonising our northern neighbour.
It’s not that China was not a threat earlier, it is just that we, perhaps, did not have an answer and hence found solace the proverbial ostrich way – “look away and the predator wont notice you”.
