If military intervention is a valid  option for Trump, I don't think it is the most time critical. He can think of the emergency powers as a more backup or last resort type option. There are still other potential options that the fake news would have a more difficult time spinning; such as Biden "saving face" and conceding. No matter what, the fake news will have to try and spin what is happening. They will try to rile people up and cause distrust, they will attack the presidency for the next four years. Now if the mil takes over the fake news with the emergency powers, that seems like a good step. Removing section 230 is also a step in that direction.
