Historian Timothy Snyder asserts that Russian President Vladimir Putin is prolonging the war in Ukraine primarily due to the influence of former US President Donald Trump. Snyder argues that Trump’s concessions paradoxically cornered Putin, fueling his determination to continue the conflict. Despite potential drawbacks, Putin’s obsession with Ukraine is deemed too strong for him to willingly seek an end to the war. The historian suggests that Putin feels compelled to persist, potentially to avoid appearing weak or conceding to external pressure. This perspective highlights the complex interplay between domestic Russian politics and international relations, specifically the role of US political figures. Ultimately, Snyder’s analysis points to a deeply entrenched commitment from Putin, independent of rational calculations, driving the ongoing hostilities.
