Talking about Americans is just a propaganda of anti-Pakistan sympathizers of Taliban kharijis. Taliban are the enemies of Muslims first and foremost.
That's your sectarian view, I don't agree with you over this. Afghan Taliban are defeating the Christian army. Paki Taliban are a different phenomena. Afghan Taliban are still supported by Pakistan to some extent. Supporting Taliban is our compulsion. If Pakistan doesn't support them, Indians and Americans will get together and crush our balls, that you will love to see I guess?
