Ok, say Godzilla is coming to town! You are the commander of the United States Armed forces. Godzilla is 400 ft tall with scales as hard as diamond and is impervious to all conventional weapons such as shells, rockets, tanks, ships, bombs, etc. He also has imense physical strength and can expell a radioactive incendiary ray which can melt or burn almost ANY substance known to man at a 300-400 yard range. He has reached the mainland and you do not want to use nuclear weapons on your own soil.....WHAT do you do to kill/repell him?!?!?
