Behind the scenes

 * In our timeline the United States' Strategic Air Command controlled the vast majority of Minuteman ICBMs.
 * The real SAC was disbanded after the end of the Cold War in 1992, but thanks to the divergence it remained essential due to the geopolitical situation (The survival of the Soviet Union into the 21st century, China's rise as a superpower, etc.)
