State Dept on what is considered Antisemitism: https://www.state.gov/defining-antisemitism/
These definitions are intentionally broad and designed to censor criticism of Israel. You have more freedom to criticize the US Government than to criticize a foreign country.
> Accusing Jewish citizens of being more loyal to Israel, or to the alleged priorities of Jews worldwide, than to the interests of their own nations.
There are plenty of dual citizens that would proudly admit that their first loyalty is to Israel.
Other examples from the document use the term "Jews as a people", whereas this example seems to apply to accusing any individual.
Although perhaps a generous interpretation of the example, is that it excludes Israeli dual citizens, because Israel would be one of "their own nations"
