Systemic tensions: How institutional power struggles between Vatican diplomacy and US militarism shape global conflict narratives

The Vatican has mediated over 150 international conflicts since the 19th century, from the 1864 mediation in the Schleswig-Holstein War to Pope John Paul II’s role in ending the Cold War. Pope Leo’s stance echoes the 1960s anti-war encyclicals *Pacem in Terris* and *Populorum Progressio*, which condemned both communism and capitalism’s warmongering. The US, meanwhile, has historically framed Catholic peace advocacy as 'unpatriotic,' from McCarthy-era attacks on Dorothy Day to modern accusations against Pax Christi activists.
The conflict between Pope Leo and President Trump is not merely a personal or partisan dispute but a collision between two institutional logics: the Vatican’s tradition of moral diplomacy rooted in *Gaudium et Spes* and the US’s militarized exceptionalism, which frames war as a tool of national interest.
Historically, the Church has mediated conflicts from the Cold War to the Iran-Iraq War, while the US has often dismissed such interventions as 'unpatriotic' or 'naive,' revealing a deeper struggle over who defines the boundaries of legitimate power. Pope Leo’s American background—rare among modern pontiffs—amplifies this tension, as his critiques of war resonate with Global South Catholics but challenge the nationalist narratives of his homeland. Marginalized voices, from Black Catholic activists to Indigenous peacebuilders, offer a corrective to this binary, framing war as a disruption to communal and ecological harmony rather than a political spectacle. A systemic solution requires institutionalizing the Vatican’s role as a moral mediator, centering marginalized Catholic perspectives, and developing a *Just Peace* doctrine that transcends the limitations of both Western liberalism and neoliberal militarism.
