Heavily armed population. The occupiers won't be fighting any organization if it occupies Pakistan. We'll just kill the occupiers every chance we get, there will be no winning our hearts. See them, shoot them. If anyone tries to win our hearts, shoot them. If anyone tries to win our minds, shoot them. An occupier smiles back at you, shoot them.
We're not Afghans or Iraqis who will welcome occupation, the worst of the worst Pakistani government is better than an occupation force that comes with rose petals.
Zero tolerance for occupiers. Of course I'd expect no less from any other nation if Pakistan occupied them. Live in peace always, but if war is imposed be ready to give the enemy a bloody nose.
Thats where you people should focus. arm the population and you wont need to worry about keepin up with India in terms of Aircraft etc.
Oh and one more thing. Nazi Germany and Imperial Japan were both occupied.
And they proved to be far better at war then Pakistan.
when push comes to shove and if the US and its Allies start diverting their full attention to war like they did in ww2 , you dont stand a chance.
