Trump II and the World / Politique étrangère, Vol. 90, No. 3, 2025
Does Trumpism exist? And if so, how can its ideology be characterized, given the myriad currents underpinning it—from populism and the Christian Right to paleolibertarianism and technolibertarianism? Does it embody a genuine worldview that informs its diplomatic actions? An obsessive drive to overturn long-standing practices, alliances, and commitments deemed “detrimental” to American interests, coupled with a fixation on transactional, one-off deals, appears to serve as its de facto strategy—hence the widespread weakening of allied ties. Observers are equally at a loss to discern an economic strategy, and above all reluctant to anticipate the possible outcomes of its contradictory maneuvers.
