If they couldn't do it in the past 250 years, what can you hope for the next 100 years? They have a highly tribalistic mindset, and co-existence and greater good are alien concepts to them. Secondly I feel that they're highly selfish in general. Like you'd hear a lot of successful Pakistanis wanting to give back to the society, hence you see the business community making universities like Lums, Ksbl etc but I have never seen an Afghan do that. It seems like they have no love for their land and community. Pakistan is economically fine right now because of patriotism and ambition of Pakistani masses. It seems like there's no such thing in Afghans.
As for their civilization, I guess its a part of their culture to not get civilized. They are a strange bunch. They'd pray 5 times a day yet see no moral and religious wrong with thievery, smuggling etc. They have this strange dog eat dog mentality. The closest they came to a proper state was during Abdali's reign, but even he had to import Punjabi khatri treasurers and finance ministers.
I think only the Farsiwans/Afghans Tajiks are capable of forming a proper state there. Majority of Islamic golden age scientists came from Northern Afghanistan, Tajikistan and Uzbekistan(known as Kwhwarezm collectively), like Al-Beruni and Al-Khwarezmi for instance; although Persians claim them for they are a complexed bunch. Muhammad of Ghaur's capital Firozkoh, was also quite well built. I think the northern Afghans and central Asians are quite capable of forming a state. It's the Afghan pashtuns who are a hopeless bunch. I think we picked the wrong side in the 90s. It did us more harm than good in the long run
PS: No offence meant to anyone. Just speaking my mind backed with facts.
