Videla was bipolar and fucking crazy. Was he abused as a kid? Something must've happened to him to cause him to go off the rails.
I think Galtieri was bipolar (And very likely schizophrenic.) and self medicated with alcohol and tranquilizers. I think Videla had some form of high functioning autism and a good amount of other neurological issues and he was thrust into the power position when he really didn't want it nor was ready for it even though he initiated it.
His body language is that of a cornered animal and when he gave speeches he could barely look at the mic much less the cameras.
I think Videla was a...natural response to the insane brutality of leftwing activists and the psycho furry and his gaggle of escaped mental patients and literal Witch Doctors that was the Tres A on the other side.
Then you have the Tacuara movement, which was basically just a bunch of upper middle class fratbros larping as Falangiast domestic terrorists..who..damn near "won" their little revolution..somehow.
Argentina had benevolent Dictators before..De Rosas, Aramburu and arguably..maybe Menem who I consider a soft power tyrant. But the Junta from the 70's was full of literal occultists and mental patients
Don't forget about the crazy Paraguayan dictator Alfredo Stroessner who was involved in the drug trade and one of his family members was on the DL I think.
Stroessner also employed more people than anyone in Paraguay's history and hilariously overthrew the Government to protect students from police brutality if I'm remembering their version of events and not the Associated Press's nonsense.
He's a fascinatingly contradictory guy. The new Milico from Guinea who overthrew that Globalist shill reminds me a lot of what I know of Stroessner.
Not that Stroessner was a good dude, just that, he was the least shitty option for Paraguay and then overstayed his welcome.
