Not to rain on your experience, but aren't a lot of Zionists in the illegal land settlements also Americans, and aren't a lot of the Jewish people participating in "birthright trips" also American?
US Jewish populations are actually really polarized on this topic, they aren't a monolith. There is definitely more of an age/generational divide regarding Zionism in Jewish communities than a nationality split.
I saw this on Reddit first while I was checking my city subreddit, damn the headline there definitely gives a different impression.
(The comments are all mostly jokes, didn't even bother wading through them and came to see If Lemmy had a thread instead).
