the Afghan army didn't really fold. You can't look at them as a regular western style army. They are basically a bunch of guys controlled by various warloards. These warlords have been around for a long time for a simple reason. they pick the side that is going to win and swap sides to whatever one that is. Right now that's the taliban but if Massoud's son manages to gather support up North then it might be a different story in 12 months time. Remember that the Afghan people have had a bit of more stable life within the bigger cities for the last 20 years so if the taliban start to behave like they did 20 years ago then the Afghans will be routing for Massoud's son.
If the same warlords start to see a shift in power then they will barter a position in the new northern alliances government and switch sides again.
I visited about 50 locations in Afghan over 6 years and the love for the deceased massoud was a bit like the british love for the Queen. It would be a very differnet country today if he hadn't been assassianted the day before the 9/11 attacks.
As for the Afghan army well I've seen them hit targets at 1200m with a dragonov which is supposed to only be good out to 700, at -22C they are running about in sandels with a pair of socks on and generally not give 2 F's when someone is shooting at them. True, some of them are idiots but then show me an Army that doesn't have its share of idiots.
Afghan is always going to be a crazy place. For the last 20 years the Russian's, Chinese and Pakistani's have had a large Western force within striking range of their borders and probably did as much as possible to undermine the Western army. Now that this is gone then the Russians will be worried about the Southern Russian states being influenced by the Taliban, the Pakistani's will be terrified that the Pashtun (the taliban are mostly Pashtun) population that is spread from Afghanistan to Pakistan and doesn't recognise the official border will cause problems in the North of the country and lastly the Chinese will be eyeing up Afghan for 2 reasons. 1 being it's full of resources that only the Chinese have the man-power to shift from Afghan to China and 2nd they will be a bit twitchy because they haven't got the best press when it comes to dealing with muslims.
If Afghan is at peace in 5 years time I'm eat my kevlar hat.
on a more personnal note, it's stange seeing the runway all over the TV as I lived in a metal ISO container for quite a long time on the edge of that runway. Right now 2 of my mates are sitting there and still in 2 minds about jumping on the next available Herc. The only reason I'm not calling them idiots is because I'm wondering how many Peq 15s, PVS 14's and ACOG's they can jam in a bag for me before getting on the next flight
