I think his death will be good for 3/4 of the world and really bad for Americans.
Like look how buddy buddy Trump was with Mamdani. Trump is susceptible to flattery and manipulation and Mamdani must have played him like a flute. So kissing the ring won't work post trump.
The Post Trump admin also wont be distracted by constantly having to jockey for his approval. Granted a new leader will probably engage in similar humiliation rituals and crony politics.
But basically with Trump butthole gone his ass kissers can focus on their work of enacting christo-fascism.
