As the longest-serving Prime Minister so far, Abe Shinzo will be remembered for the unprecedented shifts he brought about in Japan’s security policies, which will most likely have a lasting impact. From creating new institutions to fundamental changes in decision-making and from constructing a new framework for defense strategy and acquisition of offensive military capabilities to deftly managing the alliance with the US, Abe has left an indelible mark. He also came up with the Indo-Pacific construct and the Quad, which have become the key facets of regional security.
