Donald Trump has announced the imposition of tariffs on a global scale, changing the multilateral trade system established over thirty years ago.
These reciprocal tariffs are based on each country's trade deficits, ranging from 20% for Europe to 54% for China.
The retaliation of other countries could trigger a trade war of enormous consequences, slowing the global economic growth.
This decision has created legal uncertainty, affecting investments globally and creating consequences in American sectors such as academia.
Trump's new economic policy aims to address the US trade deficit, but competition is not confronted with protectionism but with structural reforms.
Countries are forced to reorganize their international trade, retaliate, and force a parity negotiation, especially the European Union that must maintain unity.
Conclusion: Trump's protectionist course introduces serious turbulences to the global economy and politics, with subsequent reactions and impacts still uncertain.
