I would say that we are now facing a 3 front scenario.
If Myanmar does not close these NE insurgent bases or will not prevent Myanmar Kuki militants from entering India (due to CCP pressure), we will have another problem. 54 people have been killed. As per reports there was participation of these insurgents from Myanmar. Most probably they will have escaped to Mizoram & from there to haven in Myanmar border.
Wish we would start done attacks against these NE militant hubs/bases in Myanmar.
Myanmar is itself at war with these Chin insurgents which is why they're escaping to India utilising the safe bases in Mizoram & now the hills of Manipur to launch attacks on Tatmadaw which in turn is complicating our relationship with Myanmar.
We can't be seen openly endorsing Tatmadaw actions against the Chin there as the clashes there though old has now assumed a different dimension which is one of an alliance of those fighting for democracy against the Tatmadaw to which these Chin insurgents have attached themselves . The more we side with the western nations on this issue to isolate the Tatmadaw the more we force them into the open arms of China who then will pursue their own agenda .
At the same time based on past experiences the Tatmadaw has proved to be extremely resilient to sanctions & equally impervious to sage counsel. In a nutshell they're the south eastern version of the Taliban with the same fanaticism minus the religion & religious indoctrination & equally stubborn.
The Home Ministry & by extension the GoI have proven to be both helpless & impotent for their explicit instructions to the state government of Mizoram to deny refuge to Myanmarese citizens mostly of Chin origin was ignored on humanitarian grounds who've now used their bases here to launch attacks on the Tatmadaw.
And now we've this royal mess in Manipur to further complicate matters.
