He’s probably ill and in recovery from his medical ailments needing to be resolved by his recent surgical procedure. He’ll make an appearance in a few weeks at latest and laugh on TV like it was all a joke.
That, or he’s too sickly to continue leading the country, in which case it goes to whoever is next in line to be party chairman.
Nobody, no matter how sick, would voluntarily give up that kinda power. But I agree that if there isn’t a death announcement by the end of this week he probably will be fine. He’s resurfaced on TV before.
