Abstract

In the process of protecting sovereignty, territorial integrity and national interests, countries with the same purpose or common enemies have joined together to combine military capabilities, Politics creates common strength to achieve the set goals. Because countries have different characteristics of population, geography, ruling class, and culture, conflicts always exist. Therefore, the fact that one country cooperates with another country to protect national security has always been common since ancient times. There are temporary, loose alliances, but there are also strong, lasting alliances. National security is ensured when there are no threats to its interests or if it is, the state has the ability to prevent and repel such threats. Countries often choose to join an alliance as a solution that brings many benefits to the country. First, an alliance will help the country replenish its strength. Because countries are always limited in resources, countries will face certain limitations when it comes to dealing with security threats on their own. With the combination into an alliance, the ability to combine powers will bring many benefits. In the context of the cold war, when the two opposing countries, the US and China, are both looking for ways to enhance their strength, expand their influence, and at the same time contain the enemy's strength, finding more comrades-in-arms is a challenge. Proving yourself is very important. To deal with growing China, the US - UK - Australia chose to ally with each other and established the AUKUS alliance.
