With those two things together you can find the relevant official's office to call.
Or do you go straight to POTUS if you want to "speak to the USA"? (also note I wrote USA and not "America")
There are many answers today to this question depending on the diplomatic rank of who‘s asking. Most obvious choices are the president of European Commission for Trump and High Representative for Foreign Affairs for Rubio. JD can entertain himself with political freaks of his choice, his reputation is ruined anyway.
You can always call von der Leyen if that's what you need to have someone to talk about. But you could have googled that yourself, so you were intentionally ignorant about that part, which makes your ragebait comment what it is: ragebait.
If this is what you want the US to be seen as, then go ahead. It's not like we're short of these kind of comments on the internet though. I can recommend to go outside once in a while, go touch some grass while reading a book.
Anyways, happy weaseling, I guess.
I think the alliance between France and Germany is as strong as never before. I think Most Germans want Macron to take the European lead right now (as we only have weak Merz to offer). Trump is like a catalyst for European unification.
PS: I‘m German.
> "Who do I call if I want to speak to Europe?"
What a silly question. "Who do I call if I want to speak to Earth? There's no such person? Therefore there is no such thing as Earth."
> So what is an "European" ??
Same thing as African, Asian, American.
