deja vu?

here you go:

Last summer, the U.S. military in Iraq, led then by Army Gen. George Casey, embarked on a plan in June to stop burgeoning sectarian violence. Casey increased the U.S. forces patrolling Baghdad's neighborhoods by 3,700, to a total of more than 15,000, and promised a canvass of the most troubled neighborhoods to root out insurgents. The Iraqi army was to lead in searching homes and securing the neighborhoods.

Military officials claimed a 40 percent drop in sectarian violence in August. But by October, violence was again out of control and the effort ended.

same story this year.
and the claims that violence went down dramatically simply have vanished.
