In his second presidency, Donald Trump has adopted an America First agenda that has had major adverse implications for public schooling and universities, and democracy and free speech more broadly in the USA. The “knock on” effects of this agenda in American universities include the freezing or removal of research funds, as well as censorship of academics. These effects are not confined to the USA alone. Instead, they are adversely impacting other liberal democracies, including Australia, where I live and work as an academic and former school administrator. In this chapter, I examine the consequences of the America First agenda through two major and interconnected planks, that is, the attacks against Diversity Equity and Inclusion (DEI) policies in schools and universities, and secondly, the thorny issue of the politicization of antisemitism on American university campuses. In terms of the latter issue—the politicization of antisemitism—I examine this through my lived experience as a secular Jew whose family fled the pogroms of Eastern Europe to find refuge in what is now Israel but was formerly Palestine. I argue that, rather than the US federal government genuinely tackling antisemitism, the politicization of antisemitism has become a useful tool in the Trump agenda that makes American Jews less safe (rather than more so) and threatens American society more broadly. I conclude by examining the implications of the America First agenda for US public education, universities, educational leaders, and scholars, as well as liberal democracies more broadly.
