Kinetic action when it comes to BD is far off. I do not believe that the GoI will go to this extent post investigation. The most that you can expect from them is that they will move to FATF and use other legal means against the BD administration. This can in turn cause a fair bit of trouble for a country that is already entangled in its own crisis. If there was logistical and other operational support, there are means, that I will not discuss here, that can be utilised.
I could do some chest beating and say initiate some action against their border provinces. However, in my opinion deportations are a good way to deal with BD. Cut out the individuals who have been mooching off the Indian states. They can continue to live their merry lives in BD. I have been repeatedly reminded by the intl. media that BD is quite progressive.
