Your challenge: make the monstrous "Process of National Reorganization" (Proceso) Argentine military coup under George Videla in the mid-late 1970s go full-on batcrap insane in the vein of the Kim dynasty of N. Korea using any divergences you wish. (In other words--multi-generational tyrannical rule, deliberate mass starvation/extermination of undesirable classes, deification of junta leaders [perhaps trying to call them living Catholic saints?], juche or "laager" mentality towards the whole outside world, total or near-total international isolation, development of credible WMDs, including ICBMs, to threaten both neighbors and Western democracies far away.)
This should be one of the easiest AH challenges as they go, as the historical Proceso regime of our TL came pretty damn close to North Korea while it lasted:
--Mass abductions of citizens by barely-disguised governmental agents
--Creation of entire undesirable classes marked for virtual elimination (leftists, Jews, etc.)
--Operation of large-scale torture and execution camps for political prisoners (and their families, just like in North Korea)
--Near-development of an Argentine nuclear bomb (some would say this was successful, but was given up when the regime stepped down after the Falklands/Malvinas War)
--Bellicose stance towards neighbors and to a lesser extent the democratic world, with some backing by the ComBloc (even though ostensibly the Proceso was an ultra-rightist regime)
--Willingness to start jingoistic wars, i.e. Falklands/Malvinas
So, how do we get from the historical 1976-84 Argentine terror junta that is today thankfully just a (very awful) footnote of that nation's troubled history, to a household name that makes suburban Americans, Japanese, etc. recoil in fear at its mere mention in 2018--a genuine threat to any and all nations near and far?
