With no end to the Iraq conflict in sight, some US military strategists have been considering tactics used during the civil war in El Salvador, a brutal and bloody campaign that lasted for years.
...The shield which stopped a guerrilla victory in El Salvador was in reality a reign of terror. Tens of thousands of those killed in the war were rebel sympathisers, tortured and murdered by the security forces. It was a well-organised, dirty war in which the CIA was heavily involved. Horrendously mutilated corpses - sometimes decapitated - were left in full public view. Using fear, the policy succeeded in denying the rebels open civilian support.
Some in the Pentagon have now been mooting the idea of training Iraqi hit squads to target insurgents and their sympathisers to quash open civilian support for them.
But for this to work would mean out-terrorising the Iraqi rebels, a difficult task indeed.
