I am disagreeing with OP.
Maintaining the edge on western border and remaining enough strong on eastern border, is right policy for us and if you observe till now we have followed this policy.
How strong is strong enough?
We have NO policy on eastern border FYI. There has been absolutely nothing done on the eastern flank while everytime someone asked the puppet PM and his Owner the question, they skipped it. We had a solid chance to build up our economy on the economic platform but they did nothing.
We don't even have enough roads in the border region for light tanks; wait, what light tanks? Even they have been pending for years together. For 30+ years, we have been asking the government to give us a mountain strike corps and a separate regiment for Sikkim. After dragging their feet for decades, finally we got it a couple of years ago. And just raising a strike core is not enough. There is absolutely nothing in logistics compared to a stronger China. We are well armed from earlier times but still nothing except special units. 80s style helmets are still visible among soldiers in the lowest of ranks; instead of using kevlar jackets, they still use the flak and ceramic heavy BPJs; no covers for joints, no net-centric capability, no night-vision equipment, oudated INSAS. I mean WTF?
Is this how the fools in the centre define 'strong enough'?
Arunachal still remains un-fenced for the 'fear of upsetting' our neighbours, a term coined by the p***y-cleaner we call our incumbent PM.
I don't say that we should hike our budget by 30% immediately because that is NOT the problem.
The problem is a pathetic, indigenous defence production.
But a sensible government coming up post elections, should focus 90% on the eastern border and 10% on the western border for at least 3 years non-stop. Built up military capability, logistics and infrastructure here for wartime as well as peace time.
