Unfortunately, there won't be any armed resistance, having India on all 3 sides is the problem. There is no way an armed resistance can sustain. It has to be a mutiny within the army.
But we are seeing army troops firing at people, so I am not hopeful at all that anyone within army will stand up.
The other alternative is international pressure. The expats need to step up and continue the pressure and get army and BAL sanctioned. Once the businesses and money starts drying up, and there is nowhere to run off to because of sanctions, may be we can get them to turn on each other.
Report coming out that the businesses are asking Hasina to turn on net as they are losing business and rmg orders going to other countries. She will be forced to get the net on, and once it happens, the news and videos of atrocities must be spread around the world.
