Gul is just a commentator? My impression is that the media flock to him as a primary source.
As pointed out, the question is whether or not the Pakistani Army are suicidal idiots. The officer denies it, but that's begging the question: simply by allowing for decades militant groups to teach and train on its territory who then attack military personnel and installations, hasn't the P.A. behaved exactly like "suicidal idiots"? And if their judgment was bad then, why should it be considered better now that they are winking their eye (if not actively supplying) at insurgents bombarding U.S. troops in Afghanistan with rockets fired from Pakistani territory, thus creating the appearance of a provocation that, if the U.S. acts, Pakistan will find no international support?
There is a distinction. The Americans did the same during the 80s by funding and training militants, who were just as zealous as they are now, to further their interests. Agreed? What saved the US was that you were thousands of miles away from these militants. So they found refuge in Pakistan and persisted. Rehabilitation of these chaps was a non-option because nobody bothered or worried about what happens to them once the Soviets disbanded and took off.
Pakistan, left with thousands of such trained militants, and herself cut off from all military and economic aid, took on these elements and used them to further her own interests with those who aligned with her. If you think that what we did was wrong, then please apply some of that very same judgment to your dealings in the 80s with these very same people.
To your point about insurgents bombing US troops from Pakistan, yes I am sure some rockets are being fired from the Pakistani territory, however how many casualties have the US troops taken? 0! On the other hand, more than 100 Pakistani paramilitary and levies troops have died in the past 3 months as a result of cross border attacks on Pakistani positions from the Afghan side. So lets realize that you cannot dump the blame on Pakistan only. Also you need to be mindful of the history, Pakistani troops will not let Afghans set up positions and move around and encroach on the Pakistan side of the border. Currently, the Afghans are using the Americans to move around in these areas and instigate a fire fight here and there and the Americans are allowing themselves to be used as pawns in this "Durrand line" issue.
The US can act, but to what end? Do you think that the Pashtun fight will end just because the US will have boots on the ground inside Pakistan?
Bottom line is that if the Americans have gripes, so do Pakistanis. In fairness there is a need to realize Pakistan's concerns. The rest like this rocket fire etc. is all tactical stuff. If you tighten up your side, there would be willingness to tighten up on our side. If the mantra is "Pakistan do more", then we have our limits. Pakistan has sacrificed her interests way more than any other country in the region and to only expect us to give up while others make merry means something is wrong with this equation.
