BD is not a front basically...and never will be. They are neither credible, nor competent. Its why we have a complete subservient leader over there actively repressing and hanging India's (and her) enemies there....and BD people are taking it like the champs they are. You literally need like a decade or two decades of a crazed islamist nutjob running affairs in BD for India to think of ramping up intervention from where it is now (and BD deciding to ramp up on their end - which is a big ask for them)....and thats not going to happen.
Basically we do not need our military to deal with BD...given without it we achieve around 50% destruction of their country which is well past what they can take before they cry uncle (which probably happens in the 10 - 20 % range...possibly even before). The 2.5 front thing has nothing to do with BD. A 0.1 "front" is more than enough to deal with them (if absolutely needed)...easily diverted from our China border theatre if required given the massive nature of the defensive advantage there (esp in winter, season we chose to directly intervene and liberate BD for a good reason in the first place)....and strategic MAD doctrine in play with that country in first place.
