Its their habit to fantasize. Even before 9/11 Taliban was never pro Pakistan, actually they were bullying Pakistan and as usual Pakistan was bending backwards to bullies. Pakistani factitious sense of bravado has pushed them (self hyphenation with Taliban) to take the responsibility of other's wrong doings.
Pakistan may not have helped them proactively as others do claim but have definitely accepted the west propaganda like a simple minded idiot and has earned the defame of siding with terrorists; rest of the world hate. Irony is, that they are still siding pretending to be their cheer leaders when they are far more clever to negotiate with anyone even India without Pakistan's consent.
At the end of this WOT world may not mock USA being defencive or negotiating with branded terrorist but will definitely blame Pakistan for openly harbouring them, doing pro Taliban lip services. This is what happened at the start of WOT when same mujahideens were said to be the creation of Pakistan not USA.
