Tell them not to worry as US terror will continue unabated in Afghanistan regardless. If not via troops then hired mercenaries or CIA death squads. The US essentially supports Taliban because they are a good excuse to stay in a country so conveniently placed within the sphere of influence of both China and Russia, so the only way for the US to be done with the Taliban is to create a new extremist force in Afghanistan--they won't solve anything by being there because that's not the real reason US troops are there. Apropos, according to FAIR:

In reality, nearly 20 years of occupation has only led to a situation where zero percent of Afghans considered themselves to be “thriving” while 85% are “suffering,” according to a Gallup poll. Only one in three girls goes to school, let alone university.

And all of this ignores the fact that the US supported radical Islamist groups and their takeover of the country in the first place, a move that drastically reduced women’s rights. Pre-Taliban, half of university students were women, as were 40% of the country’s doctors, 70% of its teachers and 30% of its civil servants—reflecting the reforms of the Soviet-backed government that the US dedicated massive resources to destroying.

Today, in half of the country’s provinces, fewer than 20% of teachers are female (and in many, fewer than 10% are). Only 37% of adolescent girls can read (compared to 66% of boys). Meanwhile, being a female gynecologist is now considered “one of the most dangerous jobs in the world” (New Statesman, 9/24/14). So much for a new golden age.
