Somehow - the above talk dovetails with some thoughts I have had.
New nuclear powers are emerging from unstable states which have huge populations of people who are barely subsisting, with governments who have little use for education, trade and development of their people - and are quite happy to hold other countries to ransom and get paid protection money in exchange. North Korea and Pakistan are the prime examples.
In this connection let me quote another para from the speech
This aspect of Indian strategic culture is common to what Kanti Bajpai described as the three streams of Indian strategic culture, namely, “Nehruvians”, neo-liberals and hyper-realists. They might differ on the best means but not on India’s strategic goals . To summarise Bajpai, all three streams agree on the centrality of the sovereign state in international relations and recognise no higher authority; see interests, power and violence as the staples of international relations that states cannot ignore; and think that power comprises both military and economic capabilities at a minimum.
If India considers the "nation state" as the highest authority it can be said that both the USA and China agree with this for themselves - i.e for their own country. They do not necessarily accept this as far as other countries are concerned. There are some fundamental requirements for a nation state to survive as an intact entity that is able to interact usefully with other nation states. A fundamental requirement is fixed and defined borders. Concepts like "immigration" "visas" and "nationality/citizenship" stem directly from the idea of a nation state with defined borders.
There 3 ways in which nations states and people can violate borders and impact upon the "sanctity of borders" that nation states require
1) People cross borders because of various reasons - economic or irredentist. This is prevented by "immigration", "border controls", "visas" and the like. In this case one or both nations do respect borders but people don't.
2) A nation disputes a border and wages military war. This often leads to "total war" between the militaries or even people of two nations. Here one or both nations do not respect the border.
3) "People's war", "guerrilla war" or "cross border terrorism". I would like to write a little bit more about this last point because it illustrates what Shivshankar Menon said
Nuclear confrontation or war between major powers is not as likely as the threat from derivatives of nuclear deterrence, namely, terrorism and nuclear proliferation, which are being used to subvert the emergence of a plural, secular and democratic international order in the twenty-first century. The challenges of a globalised world cannot be handled by twentieth century military alliances or containment strategies.
What nation states have done is to create visas and immigration controls can check illegal immigration. Powerful militaries can thwart war to change borders, upholding the sanctity of the nation state. Nuclear weapons are only an additional factor in stopping nations from trying to change borders by war.
Now if you wanted to change a border what would you do? Peaceful migration, which occurred for thousands of years is now limited by "visas' and border controls. Violent change by war is limited by militaries and nuclear weapons. The only way out is to resort to low-intensity, asymmetric guerilla warfare, also known as "cross border terrorism". Incidentally on the question of "limited war" the word "guerilla" itself means "small war"
I may be stepping OT here but there is some deeply embedded issue in the Indian psyche that is at play here. India is a great country to live in. No. I am not saying that it is better than the US and Europe - especially if you start using their definitions of what is "good" and "bad". The US and Europe have been good to live in for a mere 2000 years or less. India has been a great place for humans to live in for over 5000 years. Why. The simple reason is geography and climate. Settled human populations exploded and expanded after humans changed from a nomadic lifestyle to a settled agricultural lifestyle. India is arguably the best place on earth to support an agriculture economy. For this reason there has been a net inflow of people into India for millennia. For the same reason "Indians" do not want to leave. Indian love their land and literally do not "covet" other lands. Almost any other land is more hostile and less easy to live in. Less water, less arable land, lousy climate. Mad barbarians to boot.
Now combine the diverse points made above into one picture:
Indian are happy to keep their land. They like it there and are not trying to go anywhere. Is it any surprise that Indians see the concept of the nation state that fixes the borders of India and gives Indians a "matrubhoomi" to protect is loved by India? To quote Shivshankar Menon again:
... (Indians) agree on the centrality of the sovereign state in international relations and recognise no higher authority
It is "others", the "outsiders" who always moved in towards India throughout history. Amazingly it is still happening top this day. BRF exists because of that. But again. Look what the nation state system has done. It stops others from migrating to India as easily as they used to do 2000 years ago. Or even 500 years ago. And look what nukes and the Indian military has done? They are making it costly to wage territorial war against India.
So what is left? It is "People's war", "guerrilla war" or "cross border terrorism". These are the tools being used by everyone to subvert the Indian nation.
Indians already have a fault. They do not want to go out. Where will they go? If the try to go to Tibet - heck that is a hostile place to live. No oxygen even. If we head towards the West and cross the Indus - we get mainly desert all the way from Balochistan to North Africa. Central Asia is liveable but much less attractive than India. South East Asia is a great place. Warm, lush and inviting. Just like India. And they are full. So Indians stay put in India. India's only expansion has been towards South East Asia. The other possibility of expansion is towards Africa. Equatorial Africa is as lush, warm. moist and inviting as India.
In summary:
1) Indians are not trying to expand their territory
2) Others are trying to expand into India
3) Guerilla war is the easiest and safest route to take for expansion into India given that peaceful migration and hot war are least likely to work.
Conclusion:
We are going to have to fight campaigns against guerillas for a long long time to come. Pakistan like threats will never go away. We will have to live with them. Our defence investment will have to be in areas that fight low garde wars just as we ready ourselves to thwart "Hot, total war". Total peace at our borders will never be achieved because people will always be trying to come into India. Indians as a people have very little incentive to "go out and capture" the lands bordering India.
The possibility of 200 PAKFAs and 200 MKIs battling 1000 J 10s and JF 17s is more remote than continuous low grade war. It's not impossible - but it can be made "more remote" by making sure we have those 200+200
