ISI.
I think the real concern here is the timing of things as it relates to the new government being seated. While many, including myself, complained about Mushy not doing enough to go after AQ/Taliban, I don’t think there was active support from ISI, frontier corps, etc. It seems in the last few months that there have been several incidents, including the one at Goraparai, that seem to have support from Pakistani forces.
I don’t know if the new government is pushing this stuff or if it is just rogue ISI members (and others) who don’t fear have to fear Mushy anymore. In either case we need to fix what is happening on that side of the border if we hope to win this thing.
