Well, this is a good sign. We're operating within Pakistan's borders now (like, above-board). Eeeeexcellent. The noose is tightening around ol' OBL.
The "noose is tightening"? That's horse excrement. 9/11 was 4 and a half years ago and we're just starting to "tighten the noose."
If Bush fails to bring OBL and Zawahiri to justice during his term of office it will be one of the big strikes against his legacy, which I have every reason to believe will be fairly impressive otherwise.
