Eh, not so much. Peron was all for the cult of personality and managed to screw the country in less than a term. That’s one reason he was ousted. And for a fascist, he tried to destroy the power of the church and defund the army. That’s another reason he was ousted. He made a lot of laws that benefitted the workers and society at large, but because of being a mere reformist, he didn’t account for the ruling class being absolutely unhappy about it. That’s yet another reason he was ousted. He also put political opponents in jail, like the leader of the Radical Civil Union, which left him without political allies out of his bubble. That’s even another reason he was ousted. He then attempted to boss the Armed Forces around, and the Navy started bombing Buenos Aires until the Air Force and the Army stopped it (not without bombs falling over civilians (among others, destroying a schoolbus full of children), tanks rolling in the capital city, and jets shooting down a few bombers). And then he was ousted by a military coup which called itself “the Libertarian Revolution”, and was not allowed to return to the country until almost 20 years later. And the first thing he did when reelected was to alienate the left-wing of the Justicialist Party, which had fought for him while he was in Spain and helped to oust the dictatorship in the 60’s, and then he used the Army against them, and gave more powers to the Army. After he died, his incompetent third wife took power. And then she was ousted. This was the military coup of the '76, which was also managed by incompetent fuckwits.
So, yeah, a very very mixed bag of a president.
Arturo Illia did nothing wrong.
