I can only try,
The assassinations of Orlando Letelier, a Chilean exile, and Ronni Karpen Moffit, a US Citizen Jew (not a Chilean citizen) were part of an international terrorist ring called Operation Condor that were supported by multiple authoritarian governments in Latin America. Another target of Operation Condor was Ed Koch. The parallels with what we face today are scary. The Ford administration did squat as a response, fortunately the Democrats had a huge majority in Congress and under the leadership of Ted Kennedy slapped sanctions on the Chilean despotism, which finally gave up power in 1990. (One of the first things that the new democratic Chilean government did was to pay reparations to the US government and to the families of the victims. I look forward to Arab governments doing the same to the families of the victims of the terror they helped to sponsor, but I suspect I may be waiting a long time for that.)
