Taliban are terrorists that have publicly declared that they want to spread Jihad everywhere. We gain nothing by recognizing them right now. Only those who've had clear discussions with Taliban and arrived at some sort of line in the sand have talked about or hinted at recognizing Taliban: China, Pakistan, Iran, Russia.
.
The Taliban will be recognized by us once they beg for our recognition and prove to us that they are not planning to do a Pakistan and maintain diplomatic relations on the table and then stab us under the table by sending jihadis to Kashmir. We can handle Taliban sending waves at LoC, we don't particularly need to beg Taliban to trouble Pakistan. We can bang both Taliban and Pakistan together. Rather, we need to concentrate on snakes within. If we can take care of that, Pakistan and Taliban become small fry.
.
Also, stop looking at Taliban like a monolith. Read more about them. You've been repeating the same thing for quite some time. Spend that time to read about TTP, IMU, the fissures that appeared after Mullah Mansour became Emir, Mullah Rasool, etc. A clear structure in Afghanistan will emerge with time, our intel agencies already know more than we do. Once that structure emerges, we can begin planning its exploitation against Pakistan. Acting rashly to recognize terrorists is something that not even people as stupid as the Pakis do. We have a perception of policy consistency to maintain.
