The interrogation techniques that may be necessary to loosen Zubaydah's tongue are better administered on Pakistani soil by surrogates. I don't think Rummy should rush to bring this guy to Cuba.
Actually, reporter Lumpkin corrected his report that Abu Zubaydah had been sent to Guantanamo in a slightly later dispatch:
Capture of Abu Zubaydah could be serious blow to al-Qaida's attempts to reorganize.
So, maybe he's still in Pakistan, as you want, or maybe he's been shipped to Jordan (where he's already been condemned to death.) Remember that Yemeni microbiology student that was turned over to American authorities at Karachi airport late last year? There was recently a report that he had been shipped to Jordan.
