There are several articles on the web about how then Iraqi Prime Minister Allawi and US Ambassador John Negroponte decided to implement the Salvadoran Option in Iraq. It began with CIA hit squads, but then it continued with the US hiring former members of Saddam's secret police to form the new commandos. Here is but one of those articles, which I believe it is the earliest article WSWS published about death squads in Iraq, notice the date, a month after the fall of Baghdad.
CIA death squads operating in Iraq
By Henry Michaels

The longer the Iraq war continues, the more Orwellian the language and the more sinister the methods adopted by the Bush administration and its allies. While President Bush and his officials depict Iraqis resisting the US-led invasion as “terrorists” and “death squads,” CIA and Special Forces assassination squads are at work in Iraq, seeking to eliminate Iraqi leaders and other opponents of the US occupation of the country.
In the language of the White House and Pentagon, the thousands of Iraqi citizens in plainclothes—whether ordinary people, militia members or soldiers—who are resisting the invading forces in any way they can, are “war criminals.” But the undercover US hit squads and other military-intelligence operatives roaming throughout Iraq in civilian clothes, terrorizing the population, are “heroes” in the cause of democracy and liberation.
While the Western media has largely blacked coverage of the US killers, one report in the Canadian National Post last week briefly mentioned the presence of special operations troops in civilian clothes as US Marines reached southern Baghdad. “Special forces were also out in large numbers in their distinctive fighting gear, which includes baseball caps, jeans, expensive sunglasses and specially adapted rifles,” it noted.
There is a fundamental difference between the Iraqis who are defending their country and the US, British and Australian special operations units that are operating secretly, often in civilian disguise. Whereas the Iraqis are legitimately targeting Allied military personnel for ambushes, sniper fire and surprise bombings, the US-led squads are illegally hunting down civilians and government figures, sabotaging civilian facilities and arming selected local thugs to execute reprisals, flouting the international laws of war.
