I agree that Ukraine is different, because it was much more stable, though,I would disagree with 'popular government'; I also agree that Afghanistan had a long period of chaos; however, at some point a nation must develop this idea of responsibility and being in charge of your country's future. Afghanistan has a generation of 20 year olds who were born with relative access to education and opportunities, at least in places like Kabul and other bigger cities. They know a different life, so why aren't they fighting for it.

My country recreated itself 100 years ago, we were a part of Russian empire. Under tsar's rule my language was prohibited for 40 years and people who taught it in secret were sent to die in Siberia or hanged, but we maintained out identity and we fought. We had two brutal uprising. After brief period of independence, we were once again occupied by nazi and later on by USSR...we fought. And now we are independent again, really stable, relatively rich, part of the EU, part of NATO etc. You can go against odds if a significant number of people believe in same idea.
