Sadly, I don't think the answers to these questions are much in doubt. The bureaucrat leakers are Democrats who wanted to advance their party's interests, and the reporters at the New York Times and Washington Post were also Democrats, and were happy to oblige. The bottom line is that you just can't get adequate information from these news sources. Their grotesque biases outweigh the resources that, in theory, they are able to devote to covering the news. They can't even provide a balanced account of a single bureaucratic report, let alone of a war.
