The US has a new big plan. They stop oil ships. These ships go to Venezuela.
President Trump says ships must stop. This makes South America tense. The US took a ship too. It had oil.
The US wants to make Venezuela weak. They say Venezuela does bad things. Oil money is used for bad things.
US ships stop boats. They want to stop Venezuela's oil. Oil is Venezuela's money.
Venezuela does not like this. They say it is a threat. This will hurt Venezuela's money.
