It is not that easy to break through the international border and India will certainly think over it. million times before doing so. BD cannot be won by military operations from the air or by tank forces alone. It is people that will protect every inch of the country.
It's very easy to break through international border and super powers will not move a muscle if you don't have power or strong allies.
Look at Ukraine, what the other super /big powers did against neuclear power Russia other than criticism ( তীব্র নিন্দা?) ? Nothing.
In the end civilians aren't for protecting a nation without proper military command.
I posted METT -TC for you but you were not convinced.
Civilians play a major role ,but logistics play another major role too.
If India want to break through Bangladeshi border with all their brute force ( with western allies ) when China will wring the chicken neck , then surely India will desperately try to move it's military ( with western aid )through North Bengal to hold NE India.
So this time Chinese alliance will be safe guard for Bangladesh.
So, finally, IA troops will be bogged down in the marshland of BD and China will cherish this prospect. No wonder, the defense minister of China making a BD visit. He will be happy if BD just remains neutral. QUAD in this region fails at that.
BD neutrality means not allowing IA troops, equipment, or logistics and provisions to be supplied over land, water, and sky of Bangladesh. This makes Indian military operational capabilities very weak
Not that. Bangladesh only can help China by blocking the bay of bengal.
If China wring the chicken neck, then big powers will try to send aid through the bay of bengal.
If Bangladesh decide to block the aid , then usa will try to screw Bangladesh.
Remember they send 7th fleet in the bay of bengal, but for russian threat they didn't move further?
So if usa want to sent aid to NE , then China need the control of the bay of Bengal using Bangladeshi land.
Then it will be China west war instead of Bangladesh west if Bangladesh take Chinese side.
If Bangladesh remain neutral,
and block aid to NE by west west will screw us ,
if Bangladesh let west sending aid ,then China will screw Bangladesh, because they wouldn't want any aid through the bay of bengal.
If India get aid through the bay of bengal , what's the point of wringing the chicken neck?
So in such cases Bangladesh really can't remain neutral.
