I am talking about the period after the Soviet withdrawal and the NATO invasion. The warlords on all sides and of all ethnicities wreaked havoc on each other. If the Taliban did more harm, it was only a function of their strength, not their ferociousness.
I don't see how a Taliban commander can campaign for election with NATO forces around. I agree that their extremist ideollogy precludes democracy, and that is something that would need to be addressed. To be honest, in the short term, a more realistic scenario might be power sharing of powerful commanders. Proper democracy might have to wait until ethnic tensions defuse.
But the officer corps is predominantly NA. There aren't too many ex-Talibans in the officer corps, for obvious reasons.
Part of that might just be to present the image of fierce resistance against "infidel" invaders. After NATO leaves and they have the burden of actually delivering governance, they might be more tempered. Again, it would all depend if the external funding and backing for extremism is stopped.
Yes, this issue needs to be put to bed once and for all.
You are conflating two separate issues: religious extremism and geopolitical agenda.
It would be naive to think the geopolitical agendas will disappear. I am saying that the use of religious extremism to achieve geopolitical goals should not continue. As for the geopolitical wrangling, that is too ambitious to tackle at this point. We can talk about it, but let's just focus on the extremism for now.
