The secret of success for many Southeast Asian countries has been their choice of economic and diplomatic multilateralism. Fence-sitting between rival powers is becoming fraught. China inspires a degree of fear in the region, due to its clout and geographical proximity. And under Trump, the United States is on the offensive against the multilateral trade system, with major diplomatic consequences. Can Southeast Asian countries maintain their balance by embracing new partnerships?

South Asian leaders continue to reiterate how “central” ASEAN is to the region’s security architecture. However, in practice, the tendency is to prioritize bilateral agreements, gradually marginalizing the organization. This fragmentation is weakening regional cooperation, accentuating divisions, and compromising stability in the context of growing tensions in the Indo-Pacific. These trends are worrying at a time when Sino-American rivalries are becoming more acute.

The political and economic weight of the Gulf monarchies has increased considerably. These countries have diversified their economies and become logistic hubs, attracting large numbers of investors. They have also managed to extend their power beyond their borders. However, the wider regional fallout of the war begun by Hamas on October 7, 2023 has cast doubt on the Gulf’s stability, especially as it seems that the American security umbrella can no longer be taken for granted

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.

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 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.
