Trump 2: Challenges for the US Military Posture - Politique étrangère, Vol. 90, No. 1, Spring 2025

The distribution of operational leverage points in US strategy has changed significantly over the past two decades, with a sharp reduction. Donald Trump's distancing and repeated criticism of traditional US alliances threaten to undermine the entire architecture of the US presence in the world, beyond the concrete, real and, in particular, industrial impasses of America's military posture.

Morgan Paglia, researcher and journalist, is preparing a thesis at the École pratique des hautes études (EPHE) on military foresight and the American strategic debate.

The second Trump administration brings together a number of very different, even opposing, ideologies: far-right populism, the reactionary Christian right, paleolibertarianism, and technolibertarianism. The most visible measures taken since Donald Trump's return to the White House have been populist in nature, with the president's authority strengthened, checks and balances weakened, a form of identity politics embraced, and economic nationalism implemented.
Europe Uncovered?
As Russia continues to threaten Europe, the Trump administration is making no secret of its desire to withdraw—at least partially—from the defense of the Old

Trump II and Asia: The Wind is Picking Up…
The Indo-Pacific is a priority for the second Trump administration, which sees China as the United States' principal rival. However, Donald Trump began his second term in a rather disconcerting fashion by taking a harder line with Washington's traditional partners. He then provoked hostilities with Beijing, sparking a trade war even more intense than during his first term. The Chinese authorities have no intention of taking it lying down.

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.
