Saudi Arabia’s integration in the international arena and regional stability, notably through reducing its dependence on fossil energies, are crucial elements for the success of the Kingdom’s Vision 2030, the Crown Prince’s top priority. However, Mohammed bin Salman’s declarations in 2018 and 2021, indicating that “if Iran develops a nuclear bomb, we will follow suit as soon as possible”, combined with the recent strikes on key Iranian nuclear facilities, do not bode well for the future of the Kingdom, the region and the non-proliferation regime at large.

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.

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
Continent in order to focus on strategic competition with China. It is thus putting pressure on its European allies to increase their investment in the military sector. The NATO Summit in The Hague in June 2025 resulted in ambitious commitments by member states to increase their defense spending.

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.

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.

Since taking office, President Trump has defined and started to implement a new energy strategy for the United States (US), aimed at supporting fossil fuels, the nuclear industry, and the critical minerals sector. 

A world chessboard chopped up by the vertigo of power...

As a Catholic from the Rhineland, Friedrich Merz is heir to the CDU’s Franco-German policy, from Konrad Adenauer to Helmut Kohl and Wolfgang Schäuble. While Franco-German rhetoric and reflexes are deeply ingrained in him, their results must nevertheless be put into perspective.
