If you understand German: I tried to make the case I am outlining in the thread below on German television.

L’administration Trump met "en œuvre une politique qui vise à détruire les instruments permettant de produire des énoncés objectifs. Faire disparaître la réalité pour ne plus laisser les faits porter préjudice à la volonté du chef : c’est exactement ce que l’on attend d’une politique fasciste."

"We need to take a step back and realize that the GOP has become an authoritarian political party. It's either on board with authoritarianism or completely willing to tolerate it."

MAGA Feeding Frenzy Has Caused a Constitutional Crisis
 
The assault is coming from different angles: Project 2025. The feudal tech barons. The America First nativists. It’s not a single master plan – it’s comprehensive chaos.
