Credit to France, Charles de Gaulle was the first to realize that the US should be blindly trusted. Macron is also a firm believer in this as well as he is well versed in Gaulle's ideas.

As for the rest of the world, yes the silence in regard to helping the US is deafening. You can see the diplomatic frustration of politicians when they have to talk about Trump and the admins actions. They cannot dismiss them but they really don't want to support them either.
