Trust comes on foot but leaves on horseback....
You can only spend goodwill once... And boy, the US is burning goodwill at an insane rate right now.
Not in the least because to non US people this seems like exactly what one could/should expect when re-electing this guy.
It's not like we are better in that regards... you Dutch elected Wilders, and us Germans are falling for the AfD.
Also, a US president is VASTLY more powerful than either a prime minister in NL or a kanseller in Germany. The US is also a bigger world power than any European country by itself. So the implications are different.
The US elected him twice. With the second time being after pretty much an attempted coup. This is bad judgment on another level IMHO
And again a prime minister in the Netherlands: 1. does not have the same amount of power as NL is smaller and doesn't put as much power in one person 2. Is always the head of a coalition government in which the extreme ideas have been tabled
