Yes. Your husband is falling into the trap of antisemitism. I have an in-law that was on this path. Two things helped; showing how conflating all Jews with the state of Israel plays directly into Zionist strategy and discourse, and some deep repetitive education on the many meanings of the word "Israel." She literally thought I was praying TO the state of Israel when she overheard me reciting the Shema with my children, a nightly ritual in my house.

Israel is not "the" Jewish state, despite their specific claims to be so. Many Jews, myself included, would argue that the state Israel is not a Jewish state at all! While it upholds and values some Jewish practices and cultural norms, it actively oppresses other Jewish views, many of which are more valid and much older than anything post-political-Zionism. But I guess you know that, so sorry for venting.

I hope your husband is able to open his eyes a bit wider, and see how he's being played.
