One target is clear: Washington, DC. North Korean officials have talked about striking Washington on any number of occasions, so this does not surprise.
The other clear target is obviously Hawaii. The North Koreans spelled this out in their statement, and Hawaii is home to U.S. Pacific Command. Mele Kalikimaka.
Now, the other two targets are less clear. One is definitely in Southern California. My best guess is San Diego, which is the principal homeport for Pacific Fleet. There is a chance, I suppose, that Vandenberg Air Force Base is the target.
The last target — initially thought by many to be Austin — is the hardest one to make out. One of Kim’s generals and his hat — you just don’t see a man in a kepi anymore! — gets in the way. If the target is in Texas, one intriguing possibility is not Austin, but nearby San Antonio, sometimes called Cyber City, USA and home to Lackland Air Force Base and Air Force Cyber Command. The North Koreans have complained a lot lately about cyberattacks. It may seem odd, but North Korea is very worried about maintaining command and control of its nuclear forces. …
If one has but four targets to select, these four reflect a certain logic. North Korea is targeting both the national and theater leadership in Washington and Hawaii, as well as major U.S. military installations for naval operations (San Diego) and either long-range bomber missions (if it is Barksdale) or cyberattacks (if it is Lackland).
