Your war with {0} still rages, but now a troubling consideration has arisen in the city of {0}. There are whispers of spies and treason, and one group in particular has been singled out: those in the city who have historical or family ties to the enemy. These civilians have done nothing wrong – yet – but an undercurrent of fear and violence runs through the streets. What will you do?
A little extra police vigilance may be necessary, but all your citizens must be protected, no matter their origins.
There is a time-honored tactic for dealing with situations like these. Imprison the offending group. All of them.
They're either with you or against you. Give these people the opportunity to prove themselves by enlisting them in the armed forces.
