Tariffs from the US to Europe. Another trade war

Tariffs between America and the European Union
On October 18, tariffs on European products authorized by the World Trade Organization (WTO) entered into force. These tariffs were authorized for illegal aid from the European Union to the company Airbus.
The tariffs imposed on the European Union are 5000 million dollars and the US has focused on agri-food products, where Spain is the most affected country. Now the European Union will respond, without knowing yet how or when.
There is also illegal aid from the US to the Boeing company that has not yet been penalized and will occur in the near future.
In this current deceleration environment, the imposition of new tariffs creates nervousness in the markets about whether a trade war between the US and the European Union will begin now.
