In the 1980s, under the presidency of the cartoonishly evil Ronald Reagan, the U.S. not only trained and openly supported an El Salvador military that tortured and killed people with impunity, but then gave these psychopaths a free passage to the U.S. when their murderous ways were finally defeated by the Salvadoran people. It is only in the last couple of years that these military leaders have had to undergo deportation proceedings. But they remain in the U.S. and probably will never be deported. Unfortunately, even if they are kicked out, nothing will happen to them in El Salvador.
The U.S. has never come clean about its horrible history in Central America and probably never will.
