Well yes it's an internal affair but the thread includes china and the UN - so really it's a bit more complicated -- it may be just me, but I think External is a reflection of the Internal
US has the kind of relations it has with Muslim majority countries because of the kind of relations, or lack thereof, inside the US --- Pakistan cannot convince the world that it is actually against Islamist terrorism, because MAJORITIES actually support the ideas and behavior of the islamist terrorists.
This is the tragedy of playing the ambiguity game Pakistani style - we do it poorly, because there is no plausible deniablity --We're fighting terrorists, we're making deals with them, we're fighting them, we're making nice with them
While the rest of the world has been able to define fro themselves where they stand, Pakistan refuse to do so -- why?? Is it because they are duplicitous, double dealing ? Partially, but mostly, they are themselves just confused, they don't know how to tell right from wrong and good from bad.
About surrender -- there are other choices, Pakistan will make to make good choices again - See, friends, what you are seeing, and by "you" I mean most of you outside Pakistan and a handful inside, is "politics" being played by Pakistan's civilian and uniformed politicians -yes, the external is a reflection of the internal.
But just as a hypothetical, lets say Pakistan develop spine, kick Islamist terroriss's behind and tell the US to stick it and that Pakistan will follow it's interests - soon Senator Kerry will arrive with the usual carrots and sticks and of course the stick will be that India will get Afghanistan -- using the word India always animates Pakistanis, it seems.
Would China then support Pakistan's desire to follow her interests and these interests will mean incurring the hostility of the US and India and the Afghan and possibly the Iranian??
Pakistanis - may find the line about "internal matter" instructive.
