Well, the left made a good job killing all the intellegent people at the army
Nonsense. The leftist guerrilla at the time was nowhere near that good.
Here are some facts: During the Brazilian military dictatorship that lasted from 1964 until 1984 (20 years), the army killed about 300 to 500 people. The army claims 300, the left claims 500. In 2014, Congressional Truth Commission settled at 434 dead. That is in the space of 20 years.
From 1976 until 1982 (just 6 years), in a country with a population 5 times smaller than Brazil, the army managed to kill up to 50 thousand people. Only an institution where blind absolute loyalty is paramount would tolerate an open war against its own population at such scale. The way the dirty war was conducted in Argentina was not only morally reprehensible, but it was militarily speaking, incredibly stupid. As Brazilian general Leonidas Pires Goncalvez noted back in the late 70s on a now declassified memo, that the Argentina army was planting the seeds of its own destruction by waging an open war against its own citizens. Leftist armed insurgencies are like a cancer that needs to be removed with a scalpel. The Argentine military was trying to remove it with a chainsaw. He also mentioned that if he had ordered the army to do to the population 1/10 of what was being done in Argentina, the army would have splintered and revolted.
The fact that in Argentina, thousands of officers were willing to go along with that, shows that loyalty was everything, and the force lacked any notion of common sense. They will go along with any disastrous policies, be it the dirty war or the Falklands, without saying anything, because they were picked as officers due to the fact that they were loyal.
And we see the same logic being applied now on the case of this girl. What K want is a teenager that will be loyal and will do whatever she says, no matter how stupid and destructive those policies might be.
