Why Continue The Failure?

General Petreus (be-tray-us) is now saying that the US troop surge is work by a reduction in sectarian killings and a drop in roadside bombings…I guess the general is confusing Iraq with some other war…

Roadside bomb attacks in Iraq reach an all-time high:

"Roadside bomb attacks on American troops in Iraq reached an all-time high last month [July 2007], accounting for more than one third of all combat deaths."

Patterns of Sectarian Violence in Baghdad: doesn’t paint a pretty picture

"The distribution of unidentified bodies found dumped in Baghdad between June 18 and July 18, 2007.'

General Petraeus is expected to recommend keeping the high US troop numbers. His interim report, published last month, acknowledged attacks were continuing and the "slow progress" of establishing Iraqi security forces.

My question is....why? Failure is to continue and not learn from our mistakes. Iraq War = Failure.
