It's a little academic to be concerned about what the Taliban knew or didn't know. They protected OBL when his extradition was called for but with no treaty in place the US was whistling in the wind anyway

What is academic is calling it an extradition request. It was an unconditional demand that was not met.

Unconditional or not it is meanless rhetoric if it doesn't result in the required action. You see Tom I happen to regard a lot of what has happened as meaningless rhetoric
