Washington ? Drafts of a report from the top U.S. inspector in Iraq conclude there were no weapons stockpiles, but say there are signs fallen Iraqi President Saddam Hussein had dormant programs he hoped to revive, according to people familiar with the findings.

In a 1,500-page report, the head of the Iraq Survey Group, Charles Duelfer, will find Saddam was importing banned materials, working on unmanned aerial vehicles in violation of U.N. agreements and maintaining a dual-use industrial sector that could produce weapons.

Duelfer also says Iraq only had small research and development programs for chemical and biological weapons.

As Duelfer puts the finishing touches on his report, he concludes Saddam had intentions of restarting weapons programs at some point, after suspicion and inspections from the international community waned.

After a year and a half in Iraq, however, the United States has found no weapons of mass destruction — its chief argument for overthrowing the regime.

An intelligence official said Duelfer could wrap up the report as soon as this month. Those who discussed the report inside and outside the government did so on the condition of anonymity because it contains classified material and is not complete.

The report is expected to be similar to findings reported by Duelfer’s predecessor, David Kay, who presented an interim report last year to Congress. Kay left the post in January, saying, “We were almost all wrong” about Saddam’s weapons programs.

Duelfer’s report, however, is expected to fall between the position of the Bush administration before the war — portraying Saddam as a grave threat — and the declarative statements Kay made after he resigned.

The Duelfer report will come months after the Senate Intelligence Committee, led by Sen. Pat Roberts, R-Kan., released a scathing assessment of the prewar intelligence on Iraq.
