If peace were to sustain, the need to have such large armies, and the associated costs of placing them at borders (more than half the total force for either country is deputed to protect the line of control) would become redundant.
The media:
The people are the victim of propaganda; the media, a hostage to popular public opinion.
It is a never-ending rut where the second suckles off the first and then feeds it right back to the first. War and strife are a selling story, which brings ratings.
To the people, it is personal; the distrust stemming from years of posturing and mischief from either side, the distorted narratives history books teach to either folk, and the tumescent egos that we have inherited ensure the people are too piqued to think properly.
The animosity, therefore, perpetuates.
Mature nations of the world may have learned to live with their differences, but the ideals of forbearance are not for us.
We cannot move past the past. We cannot look beyond the belligerence.
The big picture is not for us.
