The Pew Research Center is reporting increasing public optimism about Iraq in poll results released yesterday. From the report:

Public perceptions of the situation in Iraq have become significantly more positive over the past several months, even as opinions about the initial decision to use military force remain mostly negative and unchanged.

The number of Americans who say the military effort is going very or fairly well is much higher now than a year ago (48% vs. 30% in February 2007). There has been a smaller positive change in the number who believe that the U.S. will ultimately succeed in achieving its goals (now 53%, up from 47% in February 2007).

Opinion on the critical question of whether the U.S. should keep troops in Iraq is now about evenly divided, the first time this has happened since late 2006. About half of those surveyed (49%) say they favor bringing troops home as soon as possible, but most of these (33%) favor gradual withdrawal over the next year or two, rather than immediate withdrawal. Similarly, just under half (47%) say that the U.S. should keep troops in Iraq until the situation has stabilized, with most of these (30%) saying that no timetable should be set.
