QUAD Vs AUKUS -
QUAD is The Quadrilateral Security Dialogue (QSD, also known as the Quad) is a strategic dialogue between the United States, India, Japan and Australia that is maintained by talks between member countries.
AUKUS (/ˈɔːkəs/, AW-kəs) is a trilateral security pact between Australia, the United Kingdom, and the United States, announced on 15 September 2021.
Under the pact, the US and the UK agree to help Australia to develop and deploy nuclear-powered submarines, adding to the Western military presence in the Pacific region.
While the U.S. has defense treaties with Japan and Australia, India is not a U.S. treaty ally, and India has historically resisted joining security alliances.
The Quad countries periodically conduct joint military exercises, but the group isn't a military alliance.
Meanwhile, India, Japan, and the United States continued to hold joint naval exercises under Malabar.
