Well, at least it is good to know that you understand Afghanistan's concerns vis a vis Taliban support in Pak.
There is support for Taliban in almost all ranks (some have negligible some have more), what we need as country is stop their support "officially" (whether some officers are doing it hidden or with support of some higher ups). There is lots of cleaning required but that does not mean Afghanistan itself is clean of sh!t, Afghanistan needs to wipe off all the opium fields which are supposedly providing financial support to Taliban. Does Karzai have balls to remove opium fields? I have zilch faith in his abilities.
