Mind the Deterrence Gap: Assessing Europe’s Nuclear Options
Europe must urgently confront a new nuclear reality. In recent years, Russia’s nuclear-backed revisionism has reintroduced nuclear coercion and the threat of nuclear escalation to the continent, underscoring the importance of credible nuclear deterrence. At the same time, Europe’s traditional reliance on US extended nuclear deterrence appears politically more fragile than at any point since the Cold War. Together, these developments require Europeans to think about their nuclear options.

New Cold War? What New Cold War? Confronting the Geoeconomic Fragmentation Narrative with the Data
It has become widely accepted that the world economy should be seen as increasingly shaped by forces of fragmentation, resulting from geopolitical tensions. This article takes another look at this narrative, using international trade data. While an aggregate analysis is consistent with a new Cold War narrative, whereby international trade is increasingly seen as split into two blocs, this is only a mix of very different outcomes. Far from being a widespread trend, geoeconomic fragmentation of trade flows is only significant in “hotspots”: Russia's foreign trade and China-US bilateral exchanges, and the impact is massive in these cases. Outside these “hotspots”, there is no tangible sign that geopolitical tensions have been shaping international trade patterns in terms of blocs, nor is there any hint of a trend toward nearshoring – to the contrary, in fact.
Regulatory Dynamics and Tensions in the Space Sector: Towards and Americanization of Space Law?
The development of space law has gradually evolved from a top-down normative dynamic dominated by the founding impetus of the UN to a bottom-up normativity driven by national and industrial practices. This evolution is now accompanied by growing normative competition, raising the risk of an Americanization of space law and prompting the question of a European response.
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.
Trump II: The Clash of Ideologies
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.
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.

A Transatlantic Defense Industrial Base? Two Contrasting Views
The evolving landscape of global defense cooperation has brought the transatlantic relationship between the United States (US) and Europe into sharp focus. As geopolitical tensions rise and the threat environment becomes more complex, the question of how Europe can best ensure its security while navigating its relationship with the United States has become paramount. This double feature report offers two contrasting views on the dynamics of US-Europe defense industrial relations, highlighting the challenges and opportunities that lie ahead for both parties.
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.
How the US under Trump Became a Strategic and Ideological Adversary of Europe
The Europeans' worst security nightmare seems to be coming true: on Tuesday, February 18, 2025, U.S. Secretary of State Marco Rubio and Russian Foreign Minister Sergey Lavrov met in Saudi Arabia to initiate the normalization of relations between their two countries. The meeting also aimed to set up peace negotiations for Ukraine. However, despite having the potential to affect the entire continent, the discussions took place without the Europeans or the Ukrainians being present.
Will Trumpian Authoritarianism Lead to a Constitutional Crisis?
Since his return to the White House on January 20, 2025, President Donald Trump has signed around sixty executive orders to implement his political agenda.

From nonproliferation to strategic competition: US export controls and China
Technological competition is at the heart of the renewed great-power competition that has characterized relations between the USA and China since the 2010s. The role of technological innovation in the evolution of power relations is already recognized in the literature of international relations. However, developments in US technology policy under the last two administrations raise the reverse question: how does the perception of changing power relations (in this case, Chinese technological catch-up perceived as a threat to US leadership) transform policies granting or denying access to technological innovation?
How Geopolitical Tensions Reshape Trade Patterns: Geoeconomic Fragmentation, or China’s Big Manufacturing Push?
A data-based analysis shows that widespread geoeconomic fragmentation of world trade is not visible, at least so far. In contrast, the geopolitically-motivated challenges to international coordination are striking, notably in relation with China's surging surplus in manufactured goods trade.
Kamala Harris's Economic Program
Since receiving the Democratic nomination in the wake of President Joe Biden’s decision to step aside in the 2024 American presidential race, Vice-President Kamala Harris has been striving to define her own policy platform to attract voters in the limited time remaining before the November 5th election. Since the economy is a central issue for American voters, Harris developed several propositions in that area.
The EU Green Deal External Impacts: Views from China, India, South Africa, Türkiye and the United States
Ahead of June 2024 European elections and against the backdrop of growing geopolitical and geoeconomic frictions, if not tensions, between the EU and some of its largest trade partners, not least based on the external impacts of the European Green Deal (EGD), Ifri chose to collect views and analyses from leading experts from China, India, South Africa, Türkiye and the United States of America (US) on how they assess bilateral relations in the field of energy and climate, and what issues and opportunities they envisage going forward.
Power and Financial Interdependence
The link between financial self-reliance and geopolitical power has long been debated. The unbalanced Sino-American trade relationship has created asymmetric financial ties which generate potential sources of leverage for both parties and will not quickly disappear. Absent a clarifying major crisis, it will be difficult to definitively determine which party has greater leverage.
