I won't speculate about the Pakistanis - I used to spend a lot of time on their military and political boards and rather liked them - but this is good news of a couple of fronts. Obviously removing a high level commander is good news, especially alive and talking. But rather less obvious is the joint operations aspect. Pakistan has been really ticked with Obama, and a highly successful joint operation implies that the rough edges have been knocked off that relationship - especially considering that the Pakistanis are interrogating him and not a civilian prosecutor. Things are looking up.
If what so many here are saying about Pakistani double-dealing is true, then it's triple good news. It might well mean that Obama has made progress (above Bush) with them.
