The governments of the USA, UK, Canada, New Zealand, Australia, France, Germany, Italy, Spain, the Russian Federation, the People's Republic of China, and Japan maintain a top secret facility known only by the codename 'MYRMIDON'. It contains a number of ICBMs loaded not with nuclear payloads but Marmite. The only event in which they may be deployed, under any circumstances, and with the unanimous consent of all member countries, is in the event of a Lovecraftian horror breaking through into our reality.
