“Anti-Semitism is a certain perception of Jews, which may be expressed as hatred toward Jews. Rhetorical and physical manifestations of anti-Semitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities.”As adopted in May, 2016 by the 31 members countries of the International Holocaust Remembrance Alliance (IHRA) of which the United States is a member.
Adopted examples of anti-Semitism include,
1. Accusing Jewish Citizens of being more loyal to Israel, or to the alleged priorities of Jews worldwide, than to the interest of their own nations;
2. Accusing the Jews as a people, or Israel as a State, of inventing or exaggerating the Holocaust;
3. Drawing comparisons of contemporary Israeli policy to that of the Nazis.
