The fact that BSF has thrown BGB's story under the bus indicates that GoI has chosen the Tactical option. Else they would have come up with a vague account of events leading up to the shoot out so the diplomats can 69 their way to peace.
Expect an Indian tactical response in the coming days.
The BSF version supports the theory discussed in this thread:
1. That BSF entered Bangladesh upon a BGB invitation for flag-meet.
2. The BGB commanding officer wanted to do some gandmasti and detain the one BSF person who wasn't in proper uniform
3. Sensing a threat, the BSF party walked out of the meeting and turned to return to Indian border
4. With his "command" and pride on the line in front of his subordinates, the BGB C.O. asked the BSF party to stop, and the BSF party did not respond.
5. BGB ordered to fire warning shots. BSF perceived this as an attack, responded
6. BGB was now firing back, and two of its shots hit the target, killed one BSF personnel, injured another. Since the BSF party's priority was to return to India ASAP, they didn't focus on the exchange.
What India will do now:
1. Instruct all BSF posts to remain on tactical alert.
2. Plan a punitive cross-border strike anywhere along the border
3. A tactical team will enter Bangladesh and indiscriminately kill BGB personnel
4. BSF will inflict more casualties than what BGB managed
5. Diplomats will then kick in to de-escalate the situation through their 69s, but India will go into the diplomatic engagement from a position of power, not from a position of whining.
BGB has bitten off more than it can chew. Even the Pakistanis professionally observe the sanctity of flag meets. The onus is now on India to teach Bangladesh some manners.
What makes me think all this will happen?
Ans: The BSF reports to this guy:
'nuff said.
