Trump threatens tariffs over Greenland, causing trade deal to stall

President Donald Trump has threatened to impose tariffs on several European countries over the issue of Greenland. The threats have caused a major disruption in trans-Atlantic relations.

The European Union has responded by stalling the ratification of a major trade deal with the United States. Financial markets reacted negatively to the escalation, with Wall Street sinking and companies like 3M warning the tariff threats could hurt their future earnings.
