The story...

Americans told a Pakistani diplomat about Afghan war plans, months before 9/11.

Our take...

Americans told him a great deal, if you believe his account.

Mr Naik was told that Washington would launch its operation from bases in Tajikistan, where American advisers were already in place.
 
He was told that Uzbekistan would also participate in the operation and that 17,000 Russian troops were on standby.

Mr Naik was told that if the military action went ahead it would take place before the snows started falling in Afghanistan, by the middle of October at the latest.

We mention elsewhere that no-one can confirm this story, but apart from that, does it really make any sense that America would provide so much information to the representative of a country with known Taliban sympathies?

It might do if you wanted to frighten the Taliban into giving up Bin Ladin, for instance. But then how does that fit with needing Bin Ladin free, so you could launch a War On Terror? Doesn't make much sense to us.
