South Korea’s energy-heavy industry depends on oil and gas through Hormuz, but the author (Simon Hutagalung) says that does not require sending troops or fighting ships. Diplomacy, maritime information-sharing, conflict prevention, and humanitarian work can protect cargo without folding Seoul into a U.S. war with Iran.

South Korea’s self-imposed identity as a middle power is being severely tested on the global stage in a region far removed from the Korean Peninsula.

For decades, South Korea’s heavy industries and export-dependent economy have relied heavily on the flow of crude oil and natural gas through the maritime energy corridors of the Middle East to survive. However, the strategic interests of South Korea in the Strait of Hormuz do not necessarily have to be protected by sending in troops or by dispatching naval ships to engage in combat. Rather, South Korea’s commercial shipping and other national interests could be better safeguarded by engagement in diplomatic efforts, the sharing of maritime information with other countries, conflict prevention, and the provision of........
