Iran conflict hardens North Korea’s nuclear posture

North Korea’s list of close partners keeps shrinking. After the overthrow of Bashar al-Assad’s regime in Syria in December 2024, Iran became North Korea’s sole ally in the Middle East. Now, after the U.S.-Israel strikes on Iran and Ayatollah Ali Khamenei’s death, it appears that even that once close-knit relationship is on the fritz.

The Iran crisis will reinforce the belief that nuclear arms are the ultimate guarantor of regime survival. The fate of non-nuclear “rogue” states under U.S. military pressure serves as a cautionary tale for Kim Jong Un.
