I am surprised this is still going on and that is being escalated. This war does not benefit either side.
If it goes on and a full scale war erupts, both Pakistan and Afghanistan would face economic collapse, though in different ways. Pakistan, already burdened by massive debt and dependent on IMF loans, would see its military spending soar, reserves drain, and investor confidence evaporate, likely leading to default within months. Inflation would surge, the currency would crash, and austerity would follow. Afghanistan, with almost no financial reserves or institutional support, would suffer immediate devastation, trade would halt, imports would dry up, and millions would face unemployment and hunger. Pakistan would be crippled by debt; Afghanistan by destitution. Both nations would emerge weaker, poorer, and far less stable than before.
I am not sure if both Pakistani and Afghan brothers realize this, but cheering this on is actually idiotic, this if it continues, would cripple both nations, especially Afghanistan.
