Wrong Support

Supporting Americans against Afghan Taliban proved strategically very bad for Pakistan. Reasons are as follows:

• During Taliban regime, first time the drugs were completely stopped but American occupation of Afghanistan took drugs production to its peak.
• Western border of Pakistan was safe and quite and there were hopes for peaceful resolution of the border issue during Taliban regime. Now the Western border is very insecure and the region is full of violence.
  
• Taliban had ended support for insurgency in Baluchistan from Afghanistan completely. Americans arrival in Afghanistan started it once again as the terrorists have safe haven in Afghanistan.
• Pakistan provided logistical support to Americans which resulted in the destruction of roads and bridges. Americans remain very reluctant to pay expenses, and even those expenses were named as aid. 
• During Taliban regime, at start when Americans were not too crazy about them, there were prospects of peace in Afghanistan and the return of Afghan refugees from Pakistan to their real homes. Now, situation looks dark again.

After Americans run away from Afghanistan, situation there is still not improved. Americans spent trillions of dollars and killed hundreds of thousands of Afghans. Taliban are still stronger even after death of thousands American soldiers died in action. Americans main focus was on defeating Taliban, not warfare of Afghans which might include cooperation with Taliban. Americans declared Taliban as absolute enemies and there were no compromise on that. Now Americans have learned after a decade of destruction in Afghanistan that talking with Taliban is not a bad idea.
