Here is a hit piece from the Hankyoreh describing a USINDOPACOM strategy that doesn’t exist:
A South Korean government official said, “The reason so many senior US officials are visiting South Korea and campaigning hard for a GSOMIA extension is because GSOMIA is just that important to the Indo-Pacific strategy.”
Indo-Pacific Strategy gives Japan priority over S. KoreaThe US’ previous strategy for East Asia positioned the US itself at the center with South Korea, Japan, and Australia acting as “spokes.” Fundamentally, South Korea and Japan were on an equal footing. The Indo-Pacific strategy, in contrast, involves a framework where the US, Japan, India, and Australia form a “quad” hemming China in from all sides, while South Korea, Taiwan, Singapore, Vietnam, and others are included as lower-level partners.
Under this framework, the US-Japan alliance becomes upgraded to a global alliance. In pushing through security-related legislation, Japan’s Shinzo Abe administration increased its potential for intervention on the Korean Peninsula by concocting the concepts of “situations of major influence” and “existential threat,” with an eye on direct intervention if war breaks out. Under this system, Japan would need to receive initial military information on North Korean nuclear missile launch activity through GSOMIA to attack preemptively in a scenario of imminent armed attack by the North.

You can read more at the link, but if Japan was about to face a nuclear missile attack they don’t need the GSOMIA because the US would inform them. The biggest attribute of the GSOMIA is creating a mechanism where the ROK and Japan can work together.
As far as what the Hankyoreh describes as the USINDOPACOM strategy, I have read their strategy and it mentions nothing of what the Hankyoreh is claiming. You can read the USINDOPACOM strategy at this link.
