| Pacifist | -13 or less |
After the 1.0.3 update, the political cards that increase stability - 'Fund Law Enforcement,' 'Provide Security Assistance,' and 'Declare Martial Law' - also decrease a region's militancy by some measure. It's unknown if the 'Fund Insurgency Campaign' card will have the opposite effect.
