48 hours rock around the clock

i am working on a new space technology that can obliterate an entire nation's army within 48 hours based on an ai decision tree that calculates a precision attack each hour for three hours and then a nuke on a metropolis or otherwise potently useful structure it's gonna take 48 hours to kill everyone in the world with the satellites but i'll just have to go to the space station and get lucky i'm planning for a split nanosecond successful execution time frame
