Moveon.org Ad False Claims

Moveon.org had an ad (link) run in the NYTimes Monday Sept 9, 2001 titled,
General Petraeus or General Betray Us?
Cooking the books for the White House
citing:
"And last week Petraeus, the architect of the escalation of troops in Iraq , said ”We say we have achieved progress, and we are obviously going to do everything we can to build on that progress.”"
with the following allegations:

1. "Every independent report on the ground situation in Iraq shows that the surge strategy has failed. "
2. "Yet the General claims a reduction in violence. "(cooking the books)

As proof of Petraeus' fraud, the ad links to a story at the Washington Post:
“Experts Doubt Drop in Violence in Iraq,” by Karen DeYoung. 9/6/07 l
"Challenges to how military and intelligence statistics are tallied and used have been a staple of the Iraq war. In its December 2006 report, the bipartisan Iraq Study Group identified "significant underreporting of violence," noting that "a murder of an Iraqi is not necessarily counted as an attack. If we cannot determine the sources of a sectarian attack, that assault does not make it into the data base." The report concluded that "good policy is difficult to make when information is systematically collected in a way that minimizes its discrepancy with policy goals.""

Note that General Petraeus didn't take over in Iraq until after the Iraq Study Group report cited above was published. Since the Iraq Study Group are used as credible experts in the article when assessing violence in Iraq, what is their assessment NOW? The Iraq Study Group (link) disputes both move.org allegations:

The Political Situation Remains Stalemated Despite Security Improvement
"Though violence remains at high levels, increased American military presence and refocused strategy and tactics have marginally reduced instability in parts of the country, most notably Baghdad, from the worst days of 2006."
