The WP mentions that the Pentagon has put out an opaque and misleading report concluding that Iraqis are optimistic that the new government will improve things. Except, as the Post notes, the report includes "no explanation of who was polled and how." It also has similar numbers to a previous version of the report from December, before violence spiked and the Iraqi government took months to form.
It's a good article and takes seriously the idea of trying to convey a sense of reality. Which is more than you can say for the headline: "IRAQIS BELIEVE VIOLENCE WILL ABATE, NEW REPORT SAYS;Pentagon Finds Hope Is Tied to New Government."
