Hundreds of fake civilians can’t be trained without it leaking out. Indian press is quite a draamebaaz but there are few who still report without bias and would have reported it.
Optics can work only this much.
India has told all countries trying to speak about Kashmir to buzz off and isn’t bothered about anyone.
When terrorists kill civilians such measures have to be taken. The people being trained are natives of that land. Few decades back Kashmiri Pandits were driven away by terrorists but it isn’t going to happen again.
Big scale development has started in Kashmir to bring prosperity and jobs for the natives, Muslims as well as others.
Anyone trying to spoil the effort by force would be met with double the force.
