Trump announces new tariffs on European nations and faces legal challenges

President Donald Trump has announced new tariffs on eight European nations, citing their support for Greenland. The European Union is reportedly considering retaliatory tariffs worth about 17 trillion yen in response to what it calls a 'threat' over Greenland.

In a related development, a major lawsuit challenging the legality of previous Trump-era tariffs is awaiting a potential ruling from the U.S. Supreme Court. If the court rules the tariffs were illegal, it could lead to refunds worth approximately 20 trillion yen.
