"To succeed, the Quad needs to evolve from a China-focused club of four to a group of first movers on an array of specific functional challenges. The best way to do this is for the four countries to form the core of a rotating set of problem-solving coalitions in the Indo-Pacific. This rotating roster would always include the Quad countries but would also pull in other regional partners on an ad hoc and issue-by-issue basis, depending on which countries bring the most capacity—and will—to the table."
