It might help to turn off the US news and watch this.
There are Shi’ite death squads roaming the streets of Baghdad and if you want to know how they got there, you should google “Salvador Option Iraq” and see what you discover.
Especially this article.
What to do about the deepening quagmire of Iraq? The Pentagon’s latest approach is being called “the Salvador option”—and the fact that it is being discussed at all is a measure of just how worried Donald Rumsfeld really is.
Now, NEWSWEEK has learned, the Pentagon is intensively debating an option that dates back to a still-secret strategy in the Reagan administration’s battle against the leftist guerrilla insurgency in El Salvador in the early 1980s. Then, faced with a losing war against Salvadoran rebels, the U.S. government funded or supported “nationalist” forces that allegedly included so-called death squads directed to hunt down and kill rebel leaders and sympathizers. Eventually the insurgency was quelled, and many U.S. conservatives consider the policy to have been a success—despite the deaths of innocent civilians and the subsequent Iran-Contra arms-for-hostages scandal. (Among the current administration officials who dealt with Central America back then is John Negroponte, who is today the U.S. ambassador to Iraq. Under Reagan, he was ambassador to Honduras. There is no evidence, however, that Negroponte knew anything about the Salvadoran death squads or the Iran-Contra scandal at the time. The Iraq ambassador, in a phone call to NEWSWEEK on Jan. 10, said he was not involved in military strategy in Iraq. He called the insertion of his name into this report “utterly gratuitous.”)
