NA is better than a regressive nth century ugly clowns called Taliban. Just compare the state of affairs of the two, an elected government or a bunch of gun-wielding yahoos would democratic country support. Only the former.
Your affairs with Afghanistan are purely your own making, it's not us who went to Afghanistan to fight Soviets, neither it was us who allowed US to bomb the shit out of our own country. Where is India in all these, you think if India was supporting some terror groups, that would evade the US eyes? Whom did the US accuse of funding Haqqani network, where was Mulla omar found, where was Osama f'ing Bin Laden was found, UP or Bihar or Pakistan? Who air lifted terrorists from Kunduz? After messing in Afghanistan, your country went shit. It's not India's making boi, we were watching from the sidelines you making and breaking terror groups.
Your imran Khan admitted to news papers that you trained militants in Pakistan in your own madaris. Was India involved in that? You trained terrorists to fight terrorists, now you have a situation where there are tribals joining terrorism and fighting amongst each other and then fighting you.
As far as India is concerned there was only two instances when India had their time supporting militants, one was Mukti Bahini, quite successful the other was LTTE an absolute failure. One was disbanded the other was exterminated. India learned it's lessons and took a strong stance against sponsoring terrorists and we are consistent, unlike Pakistanis or even Americans.
