North Korea revealed plans to launch missiles to Guam Last week, which is escalating the Korean Peninsula tensions. The Australian Prime Minister Turnbull said, according to the ANZUS, once Australia or the United States was attacked, two nations need to help each other. Once the DPRK launched an attack on the United States, Australia will help the United States and join the war.
