There seems to be interesting information flow on Pakistan, though there are contradictions and the picture is not clear.
Joby Warrick has an article in The Washington Post about a forthcoming piece by Steve Coll in The New Yorker magazine about India and Pakistan having made progress, but then slid away from it, on achieving a peace treaty. I am not yet able to find that article on the website of The New Yorker.
David Sanger has come out with a new book, The Inheritance, which I have not yet got, which seems to have some new information about the US/Pakistan relationship. Among other things, he seems to say that the US chose to do attacks in the badlands of Pakistan because they became increasingly convinced that the ISI was actively working with the Taliban. Here is a piece from the New York Times by him which seems to be linked to the themes of this book.
Finally, Eric Schmitt and Jane Perlez have a story in the New York Times saying that US military staff are inside Pakistan helping in the fight against the bad guys.
