ANZUS

ANZUS stands for the Australia, New Zealand, United States Security Agreement. It is an agreement between these three countries to work together to make sure they are safe and secure. The agreement was made in 1951 and it means that all three countries will help each other if one of them is attacked or if there is a big problem in their country that could harm the other countries. This means that if one country is in trouble, the other two countries will work together to help them.
