The United States sent many navy ships to the Persian Gulf. President Trump called it a "big fleet." This is a safety step. It is there if it is needed. The President also wants less anger. He will talk to Iran. This is happening now.
The big ship, USS Abraham Lincoln, is going. It is coming from the South China Sea. This big group shows a serious world problem. The US said it might fight Iran. This was after Iran stopped protests. But President Trump sounds calm now. He may not attack Iran.
Also, President Trump talked about Europe. He said he might tax goods. This is if the US cannot buy Greenland. Leaders in Europe may meet. They will talk about what to do.
Oil prices are okay. This is because Iran tensions are lower. But US taxes could hurt trade. The World Economic Forum talked about this.
The ships are to pressure Iran. They also stop attacks. The Greenland talk shows US money power. The US is using ships, talks, and taxes. This is how the Trump government acts. It makes the world unsure. We will see what happens.
