I feel sorry for El Salvador. It may now have to experience several generations of Soviet-style repression and suffering before a new regime is able to overthrow the current one. Meanwhile, thousands of families will never get to find out what happened to their loved ones in those horrifying concentration camps.
FYI, many of our (Americans') ancestors fled their home countries precisely to escape this sort of state-enacted brutality.
