The swearing in of Donald Trump marks the beginning of an era of uncertainty in the US with near-absolute powers.
This era is characterized by a new world order based on national retreat, the law of the strongest, and unilateral competition for resources.
The management of international relations will be based on transactional alliances instead of multilateralism.
Threats against European partners and possible use of force to occupy Greenland demonstrate the conditional nature of these alliances.
Trump's geopolitical impact is already palpable, exemplified by the ceasefire in Gaza and Iran's decline in the Middle East.
Conclusion: It is hoped that the business logic applied to diplomacy will result in pragmatism and negotiating capacity, avoiding a damaging trade war for global interest.
