As there is to my knowledge no controversy over the existence or the effect of the laws (Ley de Punto Final & Ley de Obediencia Debida) or Alfonsín's involvement, the burden of proof is on you to show how these mainstream historical conclusions were erroneously reached even by Alfonsin himself it seems, who to my knowledge never denied that the laws were proposed, drafted and promulgated at his instigation. The same applies to the Pacto de Olivos, the actors (Menem and Alfonsín) and the effect (constitutional changes allowing Menem to run for a second term).
Of course I'd be interested in reading some alternative analysis if you could point me in the right direction.
I don't object to the glowing tributes regarding Alfonsín's character but he served in public office in a tumultuous time even by Argentine standards and these were controversial decisions. I know the reasons given for them but I was just hoping that the retrospective political analysis in the media could have been a little less sugar coated, this hasn't been the case.
