Problem is that there were many in the military that understood this and pointed this out - they stressed the need to help the Taliban build a stronger union or let the US get a smoother transition in. But, as things happened both in the US and in Pakistan with an over excited, miscalculating and misaligned leadership within institutions they didn’t realize how much crisis the Taliban would face once they gained power and how totally ill equipped they were intellectually and otherwise to run a country.That's what I've been telling the naive and insecure both groups here simce the fall..Even if pakistan finds a friendly Talib in kabul it may not to find a friendly Talib near border area following kabul...the chain of command is broken and many groups are just working autonomously as much as they can..
Now, that they have realized that and see Afghanistan as their primary interest - Pakistani naïveté is slapping it again as it realizes that no one owes their “refuge” and “depth” anything
