Recent rhetoric surrounding the conflict in Nagorno-Karabakh has exposed an unsettling convergence between elements of the American Right and long-standing anti-Israel actors abroad.

A striking example came from media figure Tucker Carlson, who questioned why US tax dollars were allegedly being used to “murder Armenian Christians,” implicitly blaming Israel for Azerbaijan’s actions.

This claim feeds into a broader and worrying trend: the re-emergence of antisemitism within sectors of the Republican base that were once reliably pro-Israel. Antisemitism—often called the world’s oldest hatred—has adapted across centuries, from ancient persecution to medieval expulsions, pogroms, the Holocaust, and post-war violence against Jewish communities across the Middle East.
