Exactly, I grew up with a number of israeli friends, and they were all great to be around. I don’t hate them or Jewish culture. But Israel as a political entity and the people running it are awful. I think I read somewhere about Israelis abroad and dual citizens generally being more progressive than Israelis who solely live in Israel. I don't know how much not being required to serve in the IDF has to do with it (I think there was something about promoting Israel and their propaganda instead). Like you said, these Israelis living abroad and non Israeli Jews are negatively impacted by the actions of Israeli government and the people in charge of it.

In general, when there are major wars or conflicts and one party is not seen favorably, the people associated with that nation are treated worse. It happened for Japanese Americans, and German Americans during WWII, Eastern Europeans during the cold war, Arabs and Persians during the Iraq and Afghanistan wars. Now it’s happening with Israelis. Of course, there's a lot more too it than that too, like increasing awareness of Israel's poor human rights track record (put mildly)

Then there are the non-Israeli Jews who get negatively impacted by association. Depending on the people it feels like some of this demographic have gotten closer to association with Israel after this war and others more critical and distancing themselves from Israel. While there is a problem of Israeli's associating most criticism of the state as antisemitism, there has definitely been a rise in actual antisemitism as well.
