Both sides will vent their spleen with this dust up but that is far as it will go. India realizes it has the forces to conquer Kashmir but that would humiliate and make desperate a nuclear armed Pakistan. After three or four weeks of clashes, it will calm down. There will be no attempt by India to take Kashmir with a large conventional force.
Like a strike reduces internal labor pressure, Kashmir acts as a popoff valve for the india/pakistan pressures
BTTT.
