As quoted from above: "Tillerson said. There are, we believe, moderate voices among the Taliban, voices that do not want to continue to fight forever. They don’t want their children to fight forever."

Ok, Tillerson, YOU believe there are moderates who don't want to fight forever --- NOBODY wants to fight forever --- so, what is YOUR understanding regarding how long they DO want to fight; and, MOST IMPORTANTLY, for WHAT they want to fight?

Do they want to fight until they have established, as universal law, unholy sharia?
Do they want to fight until they have conquered and dhimmified all kufar?
Do they want to fight until they establish their unholy caliphate?

So, before you proceed with your plans --- also quoted from above, " ... So we are looking to engage with those voices and have them engage in a reconciliation process leading to a peace process and their full involvement and participation in the government.” --- you BETTER understand and communicate precisely what they want.
