On a historical note I believe this is the first time since the 1970's that the whole country is under one government, there are no competing factions left fighting, who could have thought 20 years after 9/11 that this is how it would end, a complete and absolute Taliban victory, not even a civil war or different factions fighting each other but one government in power, first time country has been unified in decades.
Wrong, as usual. For quite a while after the 2001 war, the Taliban controlled (at best) scraps of hillside here and the odd valley there and stayed alive largely due to their ability to regroup safely on the other side of the Durand Line.
I disagree the central government in Kabul did not exercise full control over the whole nation in the early 2000's to the extent the Taliban do today.
