This may well be the golden age of the Quadrilateral Security Dialogue (known as the Quad), the strategic grouping joining Australia, India, Japan, and the United States. Since its revival in 2017 amid rising shared concerns about China, the group has consistently defied its critics and originally modest expectations. This year, the Quad has not only survived the first major change of government among its members but has thrived—not least because India, originally the most reluctant member, is now all-in on the grouping.
The Biden administration moved quickly to dispel any concerns that it might abandon an initiative championed by its predecessor. One week after inauguration, National Security Advisor Jake Sullivan praised the Quad as “a foundation upon which to build substantial American policy in the Indo-Pacific region.”
