The fact remains that you were unable to defeat Pakistan militarily in the western theatre, even in 1971.It took just 13 days to chop you into 2 halves. You have lost siachin and run back from kargil which your troops occupied through deceit.
What you don't get is what India will do with 200 m more muslims after conquering Pakistan ? The aim is not to conquer but to keep you guys at heel.
As for Siachin and Kargil, India has lost 55% of land area of Jammu and Kashmir since 1947 in different wars.
And as for you saying that India doesn't want to conquer Pakistan, .... You would have done that already if you had the means, to avenge thousand years of slavery and invasions ... But grapes are sour
