I don't think so.it is in the nature of Islam to spread and it is highly concentrated in pakistani society as it is oneof only 2 institutions that really hold it together,other one being the army.in the case of pakistan there is also no counterbalance in terms of large population wanting prosperity, technological progress,etc as most of the population will be poor with low aspirations and will continue to be so.We keep ranting against Pakistan, which is all very well, but let us understand the underlying causes for the current mindset of the Pakistani army.
The 1962 war with China, created a deep scar in our psyche, which we have not yet got over, even though Akshai Chin was a remote mountainous area most Indians had not heard of at that time.
Now imagine if the Chinese were able to conquer the entire North East and captured an entire army comprising of 90,000 men, the acid in our souls would make it very difficult to suppress the NEED for revenge.
The Egyptians made peace with Israel, only after the 1973 Yom Kippur stalemate, when the Egyptians could declare a political victory. Even then it took 12 days secret negotiations in Camp David to arrive at an understanding in Sept 1978, which then led to a rapprochement in March 1979.
We therefore have to be prepared to endure this undeclared war with Pakistan for the foreseeable future, until something happens which the Pakistani can genuinely declare as a victory. This victory has to be real, not something that the Army routinely dishes out to their people, to keep their moral up. This has to be successfully internalized by the army brass so that they feel a semblance of peace in their hearts.
At one time Kashmir was a religious matter, today it is the symbol of the Do or Die desire for revenge. And not being in a position to do anything substantial about it, is eating away at their souls. Even if Pakistan falls apart politically, this desire will not go away. In fact, a balconised Pakistan, with 150 nukes floating around, would become an infinitely more dangerous adversary. All it takes is one Nut Case to decide that "As I sinking, let me take as many with me as possible". There is a Hindi saying that "Even God is wary of the Naked".
So we have to be always on our guard, hit them hard whenever required, and curse them as much as we want on social media, as long as we understand why Pakistan is acting the way it is.
In the case of Bangladesh,we did not incorporate it into our landmass like china would have if invaded an area or like it did to tibet.in this case also Bangladesh was started because pak cared about Islam,see above, more than the ethnic makeup of Bangladesh,east pak ,at that time and so they were completely at fault for starting it.they also had habit of starting wars before 1971 like in 1948 and 1965.
Revenge mentality is redundant at best as islamic population think the right way is if a region becomes more islamized and they would consider it evil even if you defend against them and their stately instruments like pak army,etc.so they would have this revenge mentality even if you did not seperate Bangladesh from pak.
So we should not let up and give them any victory and go for total victory using whatever we have.
Right now I think pak army is stuck because they have a burgeoning pop who have a sustainable amount of islamic influence in which no other influence can be incorporated such as other religions,atheism,etc and so they are forced or guided by this to act in accordance as it is the only thing that can legitimately topple it.
Remember the average paki is an Abdul and will never be deracinated ones you might keep as your friend in foreign countries purely from numbers and ability perspective.you will always have the Abdul breed a lot with the other guys and gals having few kids if any and also in terms of street power do I have to mention that these types will fold against the mass Abdul gangs on street.they are also backed by the army and have massive experience in fights and they are also ideologically prepared to destroy other systems and ways of life.allthis means that pak will remain an islamic shithole despite whatever we may have done in 1971 as it is a complete non sequitor.we must instead focus on degradating the capacity of pak in real terms in excersing the internal cohesive Islamism into forms that will hurt india by destroying their state by balkanization.
