There's no double talk, except for people who believe in the old propaganda. Even the American commander in Afghanistan didn't believe that Pakistan military and/or ISI were colluding with the Afghan Taliban.
Former US military commander Gen (R) David Petraeus has said that during his long association with his Pakistani counterparts and interaction with ISI as head of CIA, he could never find a convincing piece of evidence which supported the alleged double game by ISI or its explicit support to elements associated with terrorism.
No Pak role in fomenting trouble in Afghanistan, says Petraeus
I will tell you one thing, if your Govt were to sincerely work and co-operate with us, on certain matters. You will not find a better friend than Pakistan. All this insecurity regarding Afghanistan, stems from the fact that the Indians are openly allowed to operate from and conspire against Pakistan
, and that Islamabad would like to see nothing more than a friendly Govt in Kabul (which doesn't necessarily have to be Taliban-based) because the last thing we want, is our country sandwiched between two hostile neighbors. That, is the only thing we are interested in. All the former obsession with finding "strategic depth" is long gone, the atomic bomb took care of that. An unstable Afghanistan isn't in the interest of Pakistan, so destabilizing it doesn't make sense for us.
