First, that isn't true because we are securing some local Sunni allies even though the national government is stuck.
The national political situation will probably follow suit, but not on a "snap your fingers in Washington" timetable.
You are correct.
The campaign is already underway by the Dems/media. The US military surge is working, but the political situation is un-winnable. They are allowing the public to already have that ingrained in their heads that the surge has worked before General Petraeus has a chance to speak in September. By then his report will be old news, but the media will go into overdrive to reinforce that they have been telling us...that the politicians in Iraq have failed and it is un-winnable. Then, they will refer back to Bush’s ‘mistakes’, including going in in the first place. Then, they will play Cheney’s video from the early mid-nineties that show that it is an un-winnable political situation. It’s clear that the change in US strategy has been effective, but that will not stop the Dems/media on second to continue to damage the mission.
