We've been through this. U.S. credibility was demonstrated and Pakistani credibility destroyed when OBL was rooted out.
What credibility? When did the US state that OBL was in Abbottabad and Pakistan deny it after an investigation?
For the US to claim that OBL was in a vast country of 180 million people, and Pakistan to claim it had no idea where he was, is not 'enhancing credibility at the expense of Pakistan'. Indeed, since Pakistan provided critical intelligence, through arresting Khalid Shaikh Mohammed and various other AQ members and handing them over to US custody, as well as critical intelligence on the man who turned out to be OBL's courier, validates Pakistan's efforts.
The Abbottabad raid only highlights US deceit and duplicity, in that it chose to deliberately humiliate an ally to undermine it, and ignored Pakistan's significant contributions against AQ that led to the tracking down of OBL.
And that said, the fact that the US leadership outright lied to the world, in the UN and elsewhere, on the issue of WMD's in Iraq, is not by any means 'cleansed' by this distorted story of the Abbotabad raid you want to concoct.
A man who collects art need only display one masterpiece to convince people of his taste and discretion; the man proved to own a forgery is revealed as one with poor credibility and judgment. They need not be judged by the same standards in the next discussion of fine art.
The US displayed no art - it displayed deception and duplicity - it betrayed the ally whose efforts against AQ played a critical part in finding OBL. Without KSM, and the hundreds of other AQ members and god knows how much more intelligence Pakistan provided the US, AQ would not have been reduced to its current status, and OBL would still be at large.
Ungrateful, lying and deceitful wenches is what the US Establishment is better compared to, and not some 'collector of masterpieces' as you may want to fantasize about in ignoring all the sins committed by the US Establishment here.
2 wars started - one out of arrogance and a refusal to negotiate, the other on a pack of lies. Several hundred thousand innocents dead, and the body count continues to rise - trillions lost in economic damages and direct spending on wars -and you actually think that the establishment you are an apologist for actually has 'credibility' and 'taste'.
Pretty close to evil is what it is beginning to look like.
