Look, the guy might have been fantastic and sharp years ago, but mental decline at that age happens and happens fast sometimes.
The question I'm asking isn't what will be the fate of the world if he gets reelected, such an old man in office, my question is what might be mismanaged or handles poorly NOW, because we just saw how incapable he is of pretty basic stuff, and he's already at the helm of a huge counter making gigantic decisions that affect billions one way or another.
I don't wish him any I'll will, but I think there should be an age limit on political office, not to mention far stricter cognitive testing. We need our world leaders to be the sharpest, quickest, on-point minds the country has to offer.
