By no means I’m a Merkel fan, never voted for her.
But she is several leagues better than Merz. I would not even want him to be the mayor of a tiny village, because he would be overwhelmed and incapable of dealing with everyday problems, like getting the trashcans cleaned regularly.
Merz is by far the worst chancellor Germany ever had.
So, a failing disk would have caused the same disaster.
The real issue here is the apparent lack of any meaningful backup.
