The four-nation alliance was jointly formed by the United States, Japan, India and Australia. It was originally targeted at the Indian Ocean earthquake and tsunami, but unexpectedly it eventually became the prototype of an Asia-Pacific version of NATO. During US President 1 Biden's visit to Japan, the Four-Nation Alliance held a summit, which held a summit every year. Now the Four-Nation Alliance has become an important tool used by the United States to encircle and contain China. According to foreign media reports, the 2022 Four-Nation Alliance "Malabar" joint military exercise officially began on November 8. This military exercise was conducted in the sea and airspace near Japan. Regarding the joint military exercise of "Malabar", a senior official of the Japanese Maritime Self-Defense Force bluntly stated that he was directly targeting China.

Japanese media claimed that the joint military exercise of "Malabar" was aimed at the so-called "unilateral change of the status quo", which is clearly aimed at China. While the United States is constantly putting pressure on China, it is using military operations to establish deterrence. In the 2022 "Malabar" joint military exercise, the US Navy used the CVN76 Reagan aircraft carrier to participate in the operation. The joint military exercise of the "Malabar" has a history of 30 years. It was originally a bilateral military exercise between the United States and India. With the addition of Japan and Australia, the "Malabar" military exercise has become a military operation under the framework of the four-nation alliance. It can be seen from the location of the military exercise near the first island chain that this is a direct target of China.

Since 2010, the United States has had the so-called "return to Asia-Pacific". This is because China's economy surpassed Japan in 2010 and became the world's second largest economy. Therefore, the United States feels unprecedented tension. China is not Japan, and the United States cannot influence China like it controls Japan. For this reason, it has the current "Indo-Pacific Strategy". In the stage of actively encircling and containing China, the United States has won over India. Australia was originally a die-hard ally of the United States. When the United States was fighting against China, Australia rushed to the front line, including deploying military forces in 's first island chain .

In the face of the annual military exercise of the Four-Nation Alliance, the Peninsula will not sit idly by. According to news released by South Korea, the Peninsula tested the ballistic missile at the Sea of Japan on November 9, which is the Peninsula's test-fire of the ballistic missile after November 5. The Peninsula and China signed an alliance, so when the joint military exercise of the United States, Japan, India and Australia pointed at China's fingertips, the Peninsula took new actions, and once again showed its strength and confidence by implementing ballistic missiles. The Peninsula tested ballistic missiles several times in 2022, the most intense ones were seven tests in 15 days from the end of September to the beginning of October, which really made the United States, Japan and South Korea feel nervous. Recently, the Peninsula has tested medium-range missiles twice.

The ballistic missiles owned by the Peninsula can not only strike second island chain , but also have the ability to strike the United States. Previously, the peninsula had tested the intercontinental ballistic missile with a range of 12,000 kilometers, which is what the United States is worried about. Now the joint military exercise of the "Malabar" has become an important action for the four-nation alliance army to deter China. While the four-nation alliance was jointly exercising, South Korea was also holding military exercises, so the test-firing of ballistic missiles on the peninsula also had the purpose of countering South Korea's military exercises. Faced with military deterrence from the United States, South Korea and Japan, the Peninsula dares to confront head-on, and testing the ballistic missile is an important measure for the Peninsula to counter the Peninsula.
