Just 18 months into his second term and with the U.S. midterm elections approaching, U.S. President Donald Trump has generated a remarkable number of geopolitical shocks: the announcement of ¡°reciprocal tariffs¡± in April 2025, the military operation in Venezuela in January 2026 and the joint U.S.-Israeli strikes on Iran the following month.

The volatility of the Trump administration¡¯s foreign policy has become a major source of uncertainty, accelerating change in international affairs and making the global environment increasingly unpredictable.

So what changes has his administration brought to the world in its second term? How does today¡¯s international environment differ from the one before Trump¡¯s return to power? Although the administration has yet to reach the midpoint of its term and much remains uncertain ahead of the midterms, enough has occurred to warrant a broader assessment. Understanding these changes is essential to grasping the transformation of the international order now underway.
