Your attempts to impose order fail. While your state apparatus is feared, at its core it is weak and lacks the strength to suppress more than a small fraction of the population at once.
Tit-for-tat reprisals between your forces and a patchwork array of armed militias sink your homeland into a bloodbath unprecedented in your subjects’ memories. Tens of thousands die.
Eventually, vast swaths of your country (and of neighboring Iraq) succumb to a quickly growing armed group that imposes a ruthless, bloodthirsty theocratic rule on all those with the misfortune to fall within its domain.
But on the plus side, you’ve managed to retain the office of president. Well done, tough guy.
