In a very short time, there were two consecutive nuclear explosions on the territory of The United States of America. The only difference was that no one noticed the nuclear explosion at the last American rocket launch center, while the nuclear explosion on Micha Island attracted the attention of the whole world.
Precisely because it was remote and unnoticed, the Americans still didn't know that the first nuclear explosion on their homeland wasn't on Micha Island, but rather the last rocket launch center. However, they were constantly monitoring the situation on Micha Island and, when they saw on other countries' Satellite TV that the missile test on Dream Island was actually a nuclear attack with nuclear weapons, they were stunned.
