Participating nations
With the United Nations Security Council completely destroyed in the beginning of the STICK War, a global solution was called upon in the form of the HMF by the twelve remaining nations of the world. There used to be over a hundred nations, but dozens have their government completely destroyed in the STICK War. And even before the aforementioned war, a hundred more were lost to pandemics, nationwide revolutions, famines, economical collapse, and in the case of Soden and North Korania, wiped off the face of the Earth to end the war they started.
Out of the twelve remaining nations, Sakafjordur's military is not powerful enough to guarantee the island nation a permanent seat in the HMF council, whereas South Korania tried to save their own skin by refusing to join the international effort. The former nuclear superpowers - Registan, Bevelle, West Necopolis, Malkrantia and Chugoku were of course in the HMF council. The non-nuclear nations that joined the HMF - Asahi, Central Necopolis (West Necopolis suffered such an economic collapse in the midst of the STICK War that they annexed themselves to the Nazis) Lebow, Latusia, Vadine and Naussica all developed nuclear weapons in response to the ten-year war that lead to the creation of the HMF.
It took until the third year of the same war before Summers Technologies Industries joined the HMF, becoming the only non-governmental faction to join the organization. Then again, the STI already have a permanent seat in the now-destroyed UNSC.
