With the exception of superpowers or countries with billion plus people rest of us have to contend with circumstances of geopolitics to behave as you say like 'rentier' states. Japan, UK, Germany, Poland, South Korea, Turkey and more are actually far better examples of 'rentier' states than Pakistan.
I can only marvel at how you can make comment on culture with a straight face. Watch Bollywood and half of the words are Arabic or Persian, the songs are probably copies of Pakistani songs. The dress style is heavily fashioned from outside India most probably from some Muslim culture.
Most of all the entire foundation of 'Mother India' rests on using the heritage of what is now Pakistan. Gandhara, Greek Kingdoms, Harappa, Mohenjo Daro and all the rest are used by India to build up their image. Even the name 'India' is English and only has 300 years currency. 'Hind' was Persian.
So it appears rich of you to find faults in us but your entire edifice would fall apart without all the extranous inputs you use in India.
Circumstances of geopolitics is a canard. Pakistan is blessed with everything a nation can want i.e fertile land, access to Sea and a large demography.
The need to be a rentier state is the consequence of a desire of expansion and acquisition of what Pakistan does not have(Kashmir) and thus the need for conflict with India.
If only Pakistan starts getting content with what it has, it can leave those states like South Korea, Turkey, UK, etc behind in development.
As far as India is concerned, there is a reason why this region is called the Indian subcontinent. India is a vast country..so to pick and choose aspects of one region of India(north west) and to say that it is what defines India is ignorant. A mistake that most Pakistanis commit regularly because they feel more comfortable with the culture of this area. India is equally defined by the Ashoka or Chandragupta as it is by Gandhara or Taxila. The Constitution gives two official names of this country - India and Bharat.
All that aside..What is most important here is that- India does not look up to Pakistan or Afghanistan or any other country for inspiration and guidance or as pinnacle of glory like Pakistanis do towards Middle East.
That is the key difference which leads to different attitudes of the public.
However, we digress. Why is it that Pakistani analysis from everyone - senior bureaucrats to military ends up looking like a street bragging or slanging match. Why is it that Pakistan persists with repeating its mistakes again and again and not learning from them and changing tact. I await your explanation on this then if you feel mine is wrong.
You seem to be under an assumption that Pakistan being able to poke India and keep surviving is a major deal- I already told you why it is not. Pakistan acts as a rentier state - by aligning with countries that lend strength(directly or indirectly) to Pakistan for fighting with India. Same why Japan being less than 100 times smaller than China challenges them directly or Korea does to China or Vietnam does to China.
It takes no big effort to become a rentier state and challenge a bigger power. India could do it as well.
Whether it is a wise choice - is an altogether different question. There are costs that come with being such a state as well - which I am sure you realize by now.
