That may explain it but it does NOT excuse it or the consequences.
Smart people are also supposed to consider the consequences of their actions a bit more deeply than dumb people, and leaders are supposed to surround themselves with even smarter and more broadly experienced advisers to alert them to potential stupid actions and so moderate their actions to avoid harming others (as well as harming their own reputation or standing).
>>Hopefully he learns from this mistake. ...
Right: so just let smart people with a lot of power make whatever mistakes come along that damage others but face zero consequences for them beyond "we hope they learn".
That is an excuse for keeping incompetent autocrats or oligarchs in power, not a plan for a sustainable and growing complex society.
Milei should face whatever consequences apply in his country to any person loudly promoting a fraud with a large platform. But he probably will not, Such a lack of consequences should be recognized as a wrong, not merely dismissed with a shrug.
Sheesh
It will probably be dismissed.
The judiciary in Argentina is largely at the beck and call of Milei's political godfather, former president Mauricio Macri, who uses them to put pressure on his political enemies (largely kirchnerismo), and also makes them quietly drop most lawsuits against him or his allies.
Now, to be clear, it's Macri (not Milei) who has the courts in his pocket, and lately they have a strained relationship, because Macri wants better positions in government for his cadres, while Milei is instead poaching them for his own party. So it's very likely this whole mess will be just a way for Macri to remind Milei who's who, and get a few favors, after which the whole thing will go away.
I'd love to be wrong about this, and for Milei to face the music, but I don't think I'm wrong.
