It doesn't even matter if a one-match ban for a red card is excessive (it's really not). It's the apparent ability for the leader of the host country to dictate that on-pitch events must be retconned because this helps his country win the tournament (in theory, of course, irrespective of USA's actual chances of becoming world champions). If there's any disagreement about the laws of the sport, they have to be taken up after the tournament, not arbitrarily rearranged in favour of one team the day before their next game. I know you and I don't disagree on this, but it bears mentioning that the real problem is not the severity of the consequences of the guy's red card, it's the fact that the fecking president can just instruct the FIFA boss to retcon what happened on the pitch. If USA had made it further in the tournament, what would be next? It's not a slippery slope, but rather a rationally deduced likelihood, that Trump might then decree that USA be given a win for a game they lost. He is that insane, and by all apparent evidence, Infantino is also sufficiently corrupt to simply comply with a demand like that. It's such a huge blow to the integrity of football as a whole.
And worst of all, we know that this kind of privilege would never be afforded to the leaders of other countries. It's only the uniquely corrupt, despicable Trump, who stands out as one of the very worst leaders that the world has ever seen, who is inexplicably treated extra favourably by FIFA. That's what really should cost Infantino the job on the spot. He is being extra kind to the absolute very worst. That's reprehensible beyond words. We know that nothing will happen because FIFA is fully sumberged in all-encompassing corruption, but it is now correct and necessary to consider Infantino a man of no human worth whatsoever. If he was in charge of something of greater humanitarian importance than football, what would he do if instructed so by an insane dictator? Even if football is limited in its capacity to inflict evil, a man like that has shown us all what he would probably do if he was in charge of an institution that could do more harm.
