No you can't.
No one would allow that, Pakistan would defend Bangladesh.
I don't think that would be the case.
However, lets just use common sense.
BJP hates Muslims.
Doesn't matter if that means Indian Muslims, Pakistanis or Bangladeshis.
Indian Muslims I can't comment on as that's an internal Indian matter.
However, imagine a world in which you have a militarily capable Pakistan on the west and Bangladesh on the east.
Not a pleasant idea for India.
Of course, they know this and do everything in their power to prevent Bangladesh from developing its potential. (from within and now perhaps externally)
And of course we all see how India cries on the international stage when Pakistan tries to obtain weapons.
The problem for Bangladesh is there are some folks on the inside who probably facilitate the Indian agenda.
If Bangladesh buys Rafale this would be the ultimate evidence of that. (Although I acknowledge Rafale is a very potent machine and there are tactical advantages for BAF to acquire it)
Let's hope the real patriots of Bangladesh win out whatever platform BAF acquires.
For the record I think Bangladesh will buy Rafale and perhaps late block F-16s from the US at some point.
Sort of modelling UAEAF.
