These things can't be rushed, but the pace will pick up now, the thing is Bangladesh armed forces are reluctant to announce their acquisition, so it's hard to say what is going on.
You must take into account that our national aspirations and priorities are different from that of say Pakistan but things are moving in the right direction right now.
But you need to give it time, come 2030s if the vision 2030 plan formulated by the armed is followed and so far it has been, then things will be different and the power balance will change.
At this moment India is unlikely to attack Bangladesh for a multitude of reasons, least of which is that such a war would be illogical.
Greater cooperation with the Pakistani side can only be possible if your side makes the first move as our leadership is reluctant and vary of getting involved in regional power struggles.
All in all, I'll say the things aren't great right now but the picture will be different by the end of this decade, the way our economy is growing, we can field even bigger budgets soon not to mention the soft power that comes from economic strength.
I appreciate your concern about Bangladesh and your opinions are most welcome.
