What backstabbing ? Is Afghanistan your backyard ? It's a sovereign country. While you facilitated sending millions of Kalashnikovs in Afghanistan, India ran hospitals and built dams and highways in Afghanistan. And this is the result :
Afghans carry 100m long flag of India to thank India for reconstructing Salma Dam.
Why blaming others for your own mismanagement and incompetence ?
1. What do you know ? How do you know that whatever you know is right, and not brainwashing fed to you by your media, as quoted by you two posts back ?
2. Is it Pakistan's concern to begin with ? Internal issues of India ?
