A newspaper quotes a U.S. Army official as saying the military has made a "mediocre" effort in Iraq, and remains in peril of losing the war.

The Washington Post Saturday printed excerpts from an essay by Major Isaiah Wilson, who served as an Army historian of the campaign and war planner in Iraq.

It quotes Major Wilson as saying the U.S. military did not have a formal plan for stabilizing the country after toppling Saddam Hussein.

The major says U.S. forces lost their dominance in Iraq a few months after Saddam's overthrow, and that the Army still does not recognize that it is fighting what he calls a "war of rebellion."

The Wilson essay has been delivered at several academic conferences but remains unpublished.

In his recent memoir, Retired Army General Tommy Franks said a post-war plan for Iraq did exist, and expressed confidence in the plan.
