curious Yeah, only two reasons the world knows so much about about US leaders other than President and maybe Secretary of State is because the current dysfunctional situation has such global impacts and the internet can be very US-centric. I assume German speakers outside of Germany might be exposed to some of the bigger gaffes from our politicians, but all the stuff that works as expected gets fairly little attention.
Meanwhile, I would assume that if you asked Americans about who the president of Germany is, the vast majority of responses wozld be empty or nonsensical, and almost everyone who did give a sensible response would name a current or former chancellor.
