High confidence (80%)
Risk direction: escalatory · Impact: HIGH
Full prediction
Within 24 hours, the US, Japan, and South Korea are likely to increase visible air and naval patrols and reconnaissance flights around the Sea of Japan in response to the DPRK launch. Expect bomber or fighter presence announcements, additional Aegis destroyers or patrols, and rapid trilateral consultations publicized by defense ministries. This reassures domestic audiences and signals deterrence to Pyongyang but also raises the risk of air or maritime close encounters with North Korean assets. Confirmation would be new NOTAMs, aircraft spotter reports, or official statements on enhanced patrols; denial would be muted military activity and limited to rhetorical condemnation.
