AOA,
All sounds will be made that seems convincing to the pakistanis that it is not losing to India on this front. It is in the Interest of US/Karzai/India to make pakistan believe that Aal is well, wrt Afghanistan and Indian involvement.
A disgruntled pakistan will not serve the purpose of US, as I have mentioned before. And it is unlikely that US will be passive regarding the interets of its strategic ally (Bharat).
Its interesting to see karzai "awakening" so suddendly to employ a pardigm shift in his approach.
As far as the bolded part is concerned, well you must remember the relevance of the phrase , "hindi chini bhai bhai"
