The martial music concert was part of the "Day of the Sun" festivities honoring late founding father Kim Il Sung. As the uniformed brass band and choir played performed enthusiastically to an audience of clapping soldiers, a propaganda video showing missiles being launched was shown on a large overhead screen.
Eventually the nukes found their target, San Francisco, and exploded in massive fiery eruptions, engulfing the city in flames. The audience appeared to applaud San Francisco's destruction, primitive CGI production values notwithstanding.
Maybe STRATCOM can re-purpose the projectile to Berkeley, CA?
